Have 2007 jk with 4,10 and danna 44 rear. I am installing a 2 inch suspension lift and 33 x 10 tires on 16x10 rims with 4.5 backspace. ? 1 Will I have any tire rubbing issues or wheel well clearance issues. ? 2 Will I expect a big power loss because of the 33 inch tires. Any help would be nice.

 

No, you will not have any rubbing with this setup and no, you will not see a significant power loss. In fact, this is really a great setup and I think you will be very happy with it

 

33x10 tires on a 10" wide rim? I think that might be too wide of a wheel right? Seems to me since most run that size rim with a 12.5 or wider tire. If it works, you will have very little sidewall bulge to protect the wheel from rocks and such.

 

Ya know, he did say a 10" wheel didn't he?

Well, I completely agree with jeepnxj3 and I would recommend that you get an 8" wide wheel instead even if you get a 12.50 wide tire.

 

you guys are right I am using a 33x10 rim with a 33x12.5 tire sorry, but thanks for the input.

 

1 more ? have auto trans with this setup .Heard I should get my cpu flashed or updated for the bigger tires, is this true ?

 

I'm confused. What size tire is a 33 x 12.5? Is it a 305/75, or a 285/75? And does the size of the wheel make a difference? What size tire (305 or 285) would be a 33" x 12.5 on a stock 17" wheel? Finally, what would be the minimum lift to run such a tire without rubbing?

 

Tires are measured in metric and standard. Standard being 33x12.5. in this case they are talking about 33x12.5-16's (16 being the rim size) [33" tall, 12.5" wide and build for a 16" rim]

A metric 305/75-16 tire converted to standard would be about 34x12-16 and a 285/75-16 would be 32.8x11.22-16.

The width of the wheel doesn't change the tire size, it does however effect ow much of your tire and what parts of your tire touch the ground.

Midblues: I'm not sure about your CPU... anyone know?

 

If you have a stock rubi, no need to flash they already have 32 inch tires which is the max the dealership can flash up to. If you have an X than yes, you should reflash because your stock tire size is less than 32 inch., which will at least make your readings closer than no flash. Did that make sense?
