    37" tire width... 12.5 or 13.5?

    I couldnt find a convo about this anywhere so id like to hear your thoughts, opinions and reasoning as to why you would prefer one over the other.

    Edit: let me add that they would probably be going on a non-beadlock wheel with a width of 8.5-9". BS on those wheels looks to run between 4.25-4.5".

    After seeing 37x12.5r17 BFG mud terrains on a 17x9" wheel, I'd suggest 13.5s for that tall of a tire. The 12.5s are nice, but almost seem like pizza cutters

    I agree with you on the look. Wasnt sure if there were any big drawbacks to the 13.5, other than i may have some clearance issues while turning. Maybe not though...

    I wanted the Toyo Open Country M/T in the 37 x 12.5 x 17 flavor. I really wanted this tire in the 12.5" width. Couldn't find that size anywhere. I ended up with the 13.5" width. I have had some serious rubbing issues with these tires on my ATX rims with 4.5" back spacing. I added a washer under the steering stop bolts. I also added Spidertrax 1/5" wheel spacers and still rub a bit. I wish I could have found the Toyos in 12.5" width.

    i have 37x12.5.17 nitto trail grapplers on my 3.5" lift. i think they look great, but another inch would have looked really mean. i'm happy with them...that said, i do have some rubbing on my front sway bar at full turn. i may add spidertrax spacers, or i may just avoid full turning lol. if you go 13.5, you'll likely have to add spacers.

    I really want to lose the spacers. I have them on my factory wheels now with 35x12.5 tire and slight rub my lcas sometimes at full turn. If 37x13.5 is going to be a huge issue with 4.25 bs, then ill just go 37x12.5...

    yea, if you don't want to use spacers then 12.5 might be the way to go. but i agree man, 13.5 width looks really badass.
