Snowren24 cool, thanks for your help. Unfortunately it doesn't look like cooper makes the ATP or AT3 in a 17" and a 305. They go from 285 right to 315. but the 285 numbers look good, little concerned about that load rating though. wondering if would it be too stiff for a 2013 jku

LT285/70 r17 e
Rim width 7.5-9
tire width 11.4
height 32.83
tread width 9.1
load rating 121s
max load 3195

WXman Exactly. The TREAD width is what matters. Usually these listings are found on manufacturers' websites. On occasion I have emailed them through their "contact us" link to get the data I need.

Rule of thumb is you want to keep the tread width equal to, or slightly greater than, the wheel width. 285 series tires generally have about 9" of tread width. 305 series tires would be ideal for your 9" wheels of choice. But your 255s will work because like I said they run big and have 8.5" of tread width whereas most 255 series tires are only packing about 7.5" of tread width.

Snowren24 ok I see, so 255 doesn't mean the tread is 10.03 inches wide, (255/25.4) it means the side wall of tire is 10 inches wide?

So the tires I was looking at, the cooper ATPs, they were 285/70r17, if the tread wouldn't be 11.22 inches wide, how can you tell how wide it would be?

WXman The stock GY 255/75-17 tires actually run big for their size. They have a full 8.5" of tread width which is a lot more than the average 255/75 tire. So on a 9" wheel they will be OK. Not ideal...but it'll work and the tread wear should be OK with them.

If you had the stock BFGs I'd say probably don't do it.

Cool, I was thinking about going with the Cooper STT or the ATP when/if I do get another set of tires.

Snowren24 I was actually thinking about sticking with the stock tire for now, and then getting 33"s when i needed replacements.

How would the stock tires do on the aftermarket rims?

What coopers were you running there? they look good. I doubt I'll be going with 35s, not that I dont like the look, but the mpg is a concern, and I have the 3.21 gearing ( I know big mistake )

Mounah Concerning the TPMS I took them off the stock rims and put them on the RRs. It can be done easily but smoothly. I'm sure you can find some tire expert who's already done it
12-03-2012 10:58 AM
Mounah What tires are you planning to put on? If you go for 33s your stock rims will fit good but you'll feel the balloon like curve around the rims as they are 8" wide. The RR rims come in 9inch width enough to nicely wear 33s.

Aftermarket rim, stock tires? or bad idea?

I really want to go with black rims on my white 2013 JKU. The ones I've found that I like the best are these satin black rugged ridge wheels

Part Number: rug15301.01

  • Satin Black
  • 17” x 9” Wheel size
  • -12mm offset
  • 5x5” Bolt Pattern
  • 4.75” Back Spacing
  • Lifetime Structural Warranty
Now I have pretty much brand new tires on my Jeep, and from what Ive read peopel have a hard time selling these things.

GY 255 75 R17

I thought about keeping the stock tires and TPMS, but someone said that would look stupid, and I need to go with something like a 12.5 wide duratrac.

I've done a lot of read on the DTs, I love the look, but I just dont feel like its the right tire for me. My Jeep is my DD and the 12.5 wide tire seems to kill about 2mpgs. When you drive 80 miles a day, that will add up quickly.

Isnt the GY 255 75 r17 a 10" wide tire? why would it look bad on a 9" rim? is it the back spacing?

Thanks for any help.
