SUVs Chevrolet Suburban & Tahoe 2007 Tahoe 20" Wheels

You are in the Chevrolet Suburban & Tahoe Forum. Your Hosts are steve_ & tidester
We just purchased a 2007 Tahoe, my question is what is the best size tire to put on the 22's I have. The Tahoe is stock height with no plans to rasie or lower (maybe the rear) to level it out. I don't want to hack or cut any part of the wheel well. I've had a few different people tell me different sizes and I'm leaning towards 305/40 r22's but I was wondering if 45's would work. The rim is the Martin Bros Slickstar's. Any other recomendations are appreciated, I just want the best ride with no rubbing. Thanks in Advance.

Should be fine, but you might also get more substantial data from either a wheel/tire shop or other online boards.

well I just got a set of 20s for my tahoe from flea bay. 1,650 shipped. The dealer told me I would need the trans Recalibrated,  and the sensors re learned. well I did the sensors myself, no big deal.  but I was also made aware by the guy I bought the set from that, the 17's and 20's measure the same when on the vehicle, about 31" from top to bottom.  so I don't need no stinking trans recali.  the wheel is larger but the tire shorter which in turn, ends up being the same height as the 17s that was on there. the dealer wanted an extra 220 for this recalibration job crooks!!!  just to be on the safe side, I tested the deal against the mile markers on a nearby Road and all's cool plus the tahoe looks awesome with the brushed 20's on

Replying to: toecutter (May 22, 2007 2:17 pm) first number is width in mm, to convert to inches, divide by 25.4. second number is sidewall ratio (to the width) ie 55 = 55% of the width third number is wheel diameter. so to calc tire size for - say a 305/50/20 you would say 305mm / 25.4 = 12" wide x .50 x 2 (two sides to a tire) plus 20 (wheel diameter) = 32" diameter tires now you can run 15" wheels with 35" tires if you have a high sidewall ratio (lots of rubber vs lots of wheel), see the difference? my 07 silverado crew cab just got a 2" leveling kit, i tried 305/55/20's and they rubbed when i turned, so i cant go quite that big, either have to go down to 285 wide, or to 50 sidewall. any questions? |

I am wanting to upgrade from the 17" OEM rim to the 20" OEM polished rim that GM offers. I keep getting different answers as to whether or not the computer reprogramming will take care of any potential problems I may have with the ABS, Speedometer and gas milage indicator. Each dealership I've called has given me a different answer and one basically said that it isn't worth it. It seems that if I were to get a 20" rim with a lower profile tire that the overall diameter would be the same. I just do not want any issues with ABS or to void any warranties. Any suggestions would be appreciated.

| If the OD of the 20" tire is within a couple of percent of the OD of the 17" tire, then the error is probably negligible. Not sure the same can be said of the extra mass and the ABS. | |
