Its been quite a while since I did my lift and in that time I've run many tire sizes, several wheels, all different weights....including 38's

The only problem I've had was the angle of the CVs makes them wear a little fast.

Absolutely no problems with the engine and trans. No dif problems that weren't already there when I started.... seems pretty much bulletproof.

I've put 60k miles on my rig with the lift and its still strong.

Just put 265/65r17 BFG Long Trails on my stock 04 Envoy xl 4x4. They fit and look great. I don't think you could fit anything bigger though.

Newcomer to TB's Need some good advice.

As a bonus, does anybody have a good explanation of how height and width affect the need for spacers and lifts? too wide needs a spacer to clear the ball joint and a lift to keep from rubbing the wheel well on compression, and too tall needs a lift to keep from rubbing the wheel well on compression and spacers to keep from rubbing wheel well on turns? It looks like /75 is the beginning of spacer requirements, 275/16 and 275/17 starts to need a suspension lift, and 285+ needs both lifts? Am I on to anything here? I'll update as I can to keep bad info off the top of the thread...


Here's the information I could gather, assuming stock wheels (Thanks to Clayton and The Roadie!):

16"

265/75/16 - needs spacers

285/75/16 (33") - needs spacers, new wheels, suspension and body lifts, cutting/hammering to fit

17"

255/65/17 - OK w/ no lift, spacers, or mods

255/70/17 - needs upper ball joint mod, possible hammering to fit

255/75/17 - needs spacers, upper ball joint mod, possible hammering to fit

265/70/17 - needs spacers, upper ball joint mod, definite cutting/hammering to fit

285/70/17 (33") - needs spacers, new wheels, suspension and body lifts, cutting/hammering to fit

305/70/17 (34") takes all of the above, plus total dedication to being *the* tallest TB of us all. (JamesDub)



So i guess my question is what is the biggest tire i can go with an '03 trailblazer (LT 4x4) with a 2" body lift, front strut 1.5" lever, a 1.5" wheel spacer, on stock 16" wheels. Maybe someone can show me some pics of their TB with similar mods and larger tires. Like i said im new to TB's and would like some good advice.

My advice would be to go browse http://forums.offroadtb.com/ and check out the build threads. You'll find the best variety of options there, and plenty of pics to show how the vehicles look while in-progress and completed.

What is a front strut lever? I've never heard of that mentioned before, and am thinking this may not be an option on our platform?

Just wanted to make a note for those looking:

265/70/16 Michelin LTX M/S2 tires on my 2006 LS 4.2 4x4 with NO modifications.

They fit and I've had no problems, however there is evidence of microscopic rubbing on that upper ball joint. Clearance is probably about 1/4". I've put about 10,000 miles on these tires so far in hot and cold weather, on and off road, have taken them up to 108mph, and have had no issues. Love these tires. I'm pretty sure they're the widest & tallest tire possible on this 16" wheel without modifications.

So, has anyone determined the biggest tire a stock TB can wear without lifts, spacers, cutting, etc. ??

If you want to go with the 265 width, then the tires I posted above are the largest. Again, they only have about 1/4" of clearance so be cautious if using a different tire brand of the same size. I can only speak for the michelins that I have.

I have always preferred tall and narrow rather than lots of width. And since tire sizing was invented by the same person who invented women's pant sizes, (i.e. random female= "I am a size zero" me= "So you don't exist?"), I guess I will be playing with numbers and calculators.
