Just wondering how big of tires can I put on a 2003 trailblazer LS...I want to put some 18" rims and tires on it, but I dont want to mess up my vehicle in anyway...is it worth it??Thanks in advance

255/50-20 is the largest that you can go with stock rims 16", not certain about 18" rims.

RE: thanks steve

What are you looking to do? Get the most tire that you can without having to do a suspension lift, etc?

I'd take a trip down to a tire/rim shop and see if they can give you some advice. I'd be interested in hearing as well.

Transmition shift points

with 20's, will I have to have the shift points reset and the speedo?
