Looking to replace 17 " rims with after market. What size tire would give me 35's? Does anyone think I should go with 18" rims? I'm new to this...

Tires for a 17" wheel are usually lower cost and of a broader range of options. Generally, a 315/70-17 tire retains the factory "C" weight rating. 35x12.5's tend to only come in D or E ratings, which will ride stiffer. Many here, including myself, have run 315's and 35's on the factory 17x7.5 wheels. That does typically void the tire warranty, but it has yet to be an issue thats made these pages.Looking to replace 17 " rims with after market. What size tire would give me 35's?

Thank you. Just curious what would void the tire warrantee?Tires for a 17" wheel are usually lower cost and of a broader range of options.

Here's a reference pic of an unmounted 315/70-17 (metric equivalent to 35x12.5) bfgoodrich ko2 next to the still mounted and aired up factory 285/70-17 (33x11.5) ko2.
Each tire has a spec'd wheel width that it is allowed to be mounted on and be covered by its warranty. The factory wheel is 7.5" wide. Many 35" tires are wide enough that the factory wheel is below the mfg recommended wheel width.Thank you. Just curious what would void the tire warrantee?
No, it is not totally anecdotal. I had a 1995 Ram 2500 that developed a bad case of death wobble on 17 inch BF Goodrich 35s (notoriously soft sidewalls). Switching to stiffer Toyo's cured the problem completely. But in my opinion, the benefits of going to a 18 or 20 inch rim are not worth drawbacks. Death wobble has not appeared to be a big problem in JLs, and good suspension components should prevent it from occurring even on C-rated 315s.Not sure where the OP is located, but maybe similar questions.
I've not had a lot of experience with different wheel/tire combinations but have noticed that sometimes smaller rims with large sidewalls and/or soft (lower ply) sidewalls can adversely affect highway handling. Is this just anecdotal based on my limited experience, or is there advantage in a stiffer (high ply rating) tire when upsizing the tire on a stock rim?
Generally I've preferred 'C' ply rating tires for my vehicles as their lower stiffness seems to perform better in daily-driving snow conditions than 'D' or 'E', but as I consider a larger tire size in the future the impact of 315 vs 35 ply ratings on highway handling could play on the decision. Thoughts?
Like inverted said above, you have to pay attention to the minimum wheel widths for a given size tire.Thank you. Just curious what would void the tire warrantee?
I'm rolling with c-rated 38x13.5's on 17x9 wheels with 4.53" of backspace and a -12mm offset. I've yet to have any issues up to speeds a jeep shouldn't be doing. Whatever flex is happening from my 10" sidewalls, hasn't been felt enough to be any concern.Not sure where the OP is located, but maybe similar questions.

Some also carry the D rating which isn’t as soft as the C but not as firm as the E.Generally, a 315/70-17 tire retains the factory "C" weight rating.
Thats a great point you have there. Thank you, Captain Alphabet!Some also carry the D rating which isn’t as soft as the C but not as firm as the E.
LOL A-B-C delicious.Thats a great point you have there.
I'm thinking that in time, more c-rated tires in the larger sizes will be made available. There's definitely a market for it, with the ever growing number of wranglers on the road.LOL A-B-C delicious.
Well at the time I was tire shopping for a 315 in C load range, all that was available in that size were in the D or E load range. Some feel the E load range, with the stiffer rubber and additional belt, is TOO much and too harsh for our light trucks.
Interesting thought process! You’re probably right about more c load ranges being available in the future.Sticking with a C was one of the main reasons why I bypassed the pool of 37's, and ended up with the 38x13.5 pat's.
