Tire ???

Would I be able to run 30X9.50 on my 91 S-10 blazer? I don't think that I would have a power problem with my 4.3L and Leaving stock gears, But I don't know. Has anyone done this change before? Did you have any problems with rubbing when the suspension is flexed. I am also considering turning my TB's up about an inch and adding a nother leaf in the back, would this be needed if I went to the 30's? Or is all of this crazy and I should stay with the stock 235's?

As far as tires I think i'm going with BFG A\T. Have you guys had any problems with these?, and Is there a better tire out there for better money? Hope this all makes since! Thanks, Mike

Re: Tire ???

30's should be fine with the t-bar crank and add-a-leaves, you would be in your best interest to do those things first instead of slappin on the 30's then seeing what needs to be done. As far as power and gears, you should be just fine. I have 31's on my blazer with stock gears, and it is still pretty quick for an SUV, I have 3.42 gears, I have also done a few performance mods (K&N Gen II, Dynomax exhaust) but nothing huge, I ran 30's on my sonoma for a while, and it did just fine with the stock 4.3

Re: Tire ???

You shouldnt have rubbing or power problems. My brother had a 92 and ran 30's. He had the 4.3, 5 speed manual, and 3.42 gears and still had plenty of power. I got an 89 with 2.8 and I never have had rubbing problems with no TB crank or aal's. However I do suffer from lack of power but I did that with the stock tires too [img]/wwwthreads_images/icons/laugh.gif[/img]. The BF AT's are in my opinion the best all around tire you can buy. I dont run anything else. They wear real good and drive great. The dont do real good in mud though. If you plan to do a lot of off roading in mud you might want to consider a mud tire.

Re: Tire ???

I've got the 30x9.50 BFG All-Terrain KO's on my '98. I bought it used with the body lift, but their looks to be plenty of room for that size tire. At 31's they'll tend to rub a little.

As far as power, my 3.42 gears are enough (for now at least) running this size tire. Any bigger of a tire and I'll end up changing gears (which I plan to do anyway when I get a lift installed).

Cranking up your torsion bars is OK for some things. The ride will be stiffer, and if you're not careful as to how much you crank them up you will tend to wear out CV joints.
