The time will be drawing near for my tire purchase. I've been looking at a 285 or 295-70 17. I just saw a 34 10.50 that the say measures around 33.5". They are the KO2. I normally don't care so much about tires but I'm taking my time on the decision now.

Not being rude to you guys, but I don't want to hear how great 35" or 37" tires are. Im not in a position to re-gear so I'm not getting 35's.

I'm assuming because of the weight of the tires, the 34-10.50's would be the same as the 35's, meaning a re-gear would be in store.

Sorry for the 47,897,765,534 tire question. I know a lot of people ask about them. I usually just buy my vehicles equipped and ready to roll. This one is stock so I can enjoy adding stuff.

Just to be clear, you do not NEED to regear when you go up in tire size. It helps in a lot of ways but it is not needed. Its also not the weight that creates the desire to regear, it's the rolling diameter of the tire.

Now, to be honest I don't understand what you are asking. Do you want people to confirm the actual tire size of the 34x10.50/17s or something else?

I had 285/75/16 On my old 2 door, they only measured 32" mounted. I was running a 2.5 budget boost with no wheel spacers, they rubbed the sway bar when turning tight.
I will be putting 35" on my JKU

I have 295-70-17. For these on a unlimited, you will need to regear. Otherwise very sluggish.

10.5 - is a skinny tire. I would stick to 12.5

I have the bfg ko2 34x10.5x17, they are around 32.5 in on the ground. I was hoping for a little bigger, my friend just got the 35s and are about 1.5 in larger. Gas milage the 34s are about stock, I have 3.21 and they are ok, downshift for hills tho.

I'm going to disagree with you on the "need" for the regear and revert back to Mr. Ty's earlier statement. I'm running 315/70r17's and don't feel that I need it. Mine is DD and it does fine. Do I WANT a regear? Yes. To say that it needs a regear is somewhat of a misleading statement, when in fact, they are very driveable on a day to day basis.

On a side note, I'm still unclear on what the OP is trying to get answers on. Maybe we'll get some clarification soon.

Sorry I was vague Guys, looooooong night in the patrol car, lol. Pretty much, I have a 255 size stock tire now. I'm getting bigger tires and am staying in the 33" range for a lot of reasons. I was browsing tires and saw this 34 10.50. I guess my question was on the tire size and gearing.

I'm going to lift my jeep around 2", nothing major, and I will be adding tires. I would like to know a good tire size, in yalls opinion, that wouldn't kill my power and have the need to re-gear. Would I be better staying in the 285/295 range or could I run this 34" or the 315 and still be okay?

Also, my off-road time will be sand at the beach, light trails, mud. No rocks around these parts for me to play on.

Again, I'm sorry for the vague or confusing OP. 16 hours in a charger dealing with ding dongs all night makes it difficult to form coherent thoughts, lol

01-12-2016, 06:04 PM
Oh and thank you for the clarification on re-gearing. I understand it may not be "needed" but I don't want to struggle to roll through sand or a mud hole either.

This is why I've turned to you guys a few times now with some questions. All my answers are fairly consistent and allows me to better understand the issues or questions I have. Unlike some folks or places that swear a 4" lift and 37's are a must or your jeep is pointless, hahaha.

You guys on this forum get it, not everyone has a need or is in a position to run huge tires and lifts on their rig.

Thank you again!

I would stick with the 285/295 (33") tire range. That will be a happy medium without really needing to regear. 315s? That would be doable but will you be happy overall w/out regearing most likely not (at least for me it wasn't.) Plus with a 2" lift you may have to trim your fenders, etc and that would be a whole other aspect when running 315/35s....

Thanks bud. It's definitely not a job for everyone. Low pay and long hours usually drives folks away from it. I'm 3rd generation in my family so its second nature to me really.

I can tell you all this though, WJCO's simple thank you means the world to us out here. Reading this forum and driving my jeep listening to music is my escape so it's nice to come here and see that there are like smart asses out there!!! Lmao

Thanks again!

I put 285/70r17s on my 2008 X four door. It was the 3.8 and a 6 speed standard. I didn't feel a difference as far as driving it in the terrain around here. I did not wheel that jeep all that much. Nothing even notably really either. Just for reference, I also had wheel spacers since I had factory wheels and was starting to look into a leveling kit at minimum due to rubbing the fender flares. I didn't want to cut them yet as I didn't know on how much lift i was going to do etc.

I traded it in on my 2014 Rubicon four door, it has the 3.6 and 5 speed auto. I made sure to get one with 4.10s as I wanted 35s as soon as I could. A lot of people seem to re-gear even with 35s. For what I do and the daily driving this jeep sees, I feel like the 35s and 4.10s are about right. The only time so far that I was wishing for different gears or a standard trans was when we were going between Durango and Silverton Colorado. On the highway it wanted to stay at a high rpm and a low gear to try and keep speed. So I would usually bump it up a gear and just slow down, not too big of a deal but if I lived there I would definitely look into re-gearing for the 35s. Once on the passes it was fine, no issues crawling. I want to go to 37s soon but will probably stay with the 4.10s until I can re-gear. My commute now isn't bad so I bet I wont even notice a difference.

I say get what tire size you want and then drive it to see if you feel like you need to re-gear. Being that you have a Sport I will say that you will most likely want to regear for 35s. So you may stick to 33s. I would look into a 33x12.50 though as the wider tire will help you out on the sand more. Bigger foot print. :thumb:

^ This is a good point. Where I live, I am very biased and would lean toward a re-gear for sure.......with that being said, I'm in the mountains a ton, and notice it too often. If you're not dealing with steep climbs on a daily basis, re-gearing may not even be worth considering if you don't want to deal with the $.

The 34"x10.50" ko's your referring to do not measure even close to what bfg states on the website. They actually measure out at 32 1/4"
I had a set and returned them because they were not as advertised in their sizing. They would be an almost perfect tire to replacement for stock rubicon mud terrains if you were not wanting to change tire size. They looked very silly underneath a jku with 3" of lift.

01-12-2016, 10:19 PM
I can't speak for the 34 10.50s but I have been happy with my 285/70s so far they've held up well and I haven't felt the need to regear I'm not sure how gearing an automatic vs a manual goes but I have 3.73s in my 6 spd I originally wanted 285/75/17s for the extra bit of height because the two tires I was looking at were the same price but then I got a smokin deal on the 285/70s

My buddy who I wheel with a lot up here in Maine he runs 33/1050/15 bfg at ko on his TJ and we go everywhere the guys with the 35 37 and 40s go UP HERE. Now your mileage will vary depending upon what you wheel. We do woods trails, some small rocks snow and some mud.

I'm kinda asking the same question as reelsilly but I'm wanting to run a 315/75/16 and I will be re-gearing while I change tires I climb a lot of hills living in the high desert and out where I work. I have stock 3.21 gearing now and was thinking about 4.88s would this be an ideal gearing for me? Again I drive up and down highway hills a lot aha. I can really feel the power lose and am running very high rpms. My current tiers now are 285/ 75/16. Also if anyone has pictures of there jeep sitting on a set of 315/75/16s I would love to see them. Oh and if your wondering my lift is a 2.5 inch rubicon express with cut fenders. Thank you!

Hey aldaman thanks for posting a pic but for some reason I can't view the pic. I'm really looking forward to seeing what they look like. That's also the tire I was thinking g about either them or the nitto trail grapplers. Who do you like them and how many miles do you have on them now? I read they last a long time.

So you're saying even with the 285 size tires you're loosing a lot of power and running really high RPMs? I'm going to assume that it is because of the type of driving (location), as to why you're loosing power??? The RPMs, I wouldn't have thought would be much higher running a 285. I'm not what you would call a smart fella when it comes to that so maybe someone will chime in that would know.

You can run a 285/70 but don't bump up to a 285/75/17. I bought some nitto terra grapplers in 285/75r17 and they measured 33" mounted with 22psi. That is basically the same size as an advertised 35x11.5. So I ended up at off road evolution getting it new gears. I had 3.21 like you and with the new tires my auto tranny was working way too hard. 4Lo was also way to fast to crawl in. Here's a pic for reference 182186

Yeah I was thinking that's weird because there not that big of a tire. But man driving the high way it's just struggling driving a lot of high way hills. It has a hard time getting up to the speed limit. If anyone can point me in the right direction for gear ratio that would be awesome. So my plan is 315/75/16 tires. I have an 09 wrangler unlimited X stock gearing also an auto trans. What would be the best gear ratio for DD high way and mild trail runs? Thanks!

With all the info I have, I'm going to pull the trigger on a set of 285 70r 17s. Now I gotta pick a brand. Seems a lot of folks up here love the big ko2. It's either them, the Deegan by MT, or Nitto Trail Grapplers.
