I'll post a picture of a truck I just bought. 96 Chevy. Right now it has 35/1250/r15 tires. The rims are 10. I was wondering if I should keep these tires or do something like 35/1050 or 33/1050. What do you think? I've heard these bigger tires can be bad on them.

 

35's can be pretty rough on a truck that has a 4l60, 10 bolt rear, and 3.42 gears. Not to mention killing fuel mileage and performance. I'd say verify your drivetrain, most importantly what the gear ratio is in the axles , then decide how to proceed.

 

I'm not the best or skilled mechanic by any means. I've heard they're tough on the tranny like you said. I'm not sure if it a 10 bolt rear. Bunch of aftermarket like a serious pro suspension lift was installed and a tuner. I can get someone to help me verify the gear ration in the axles sometime, however would it just be easier to get 33s? They're better for the trans anyway right?

 

think a trans cooler would help?

 

Be patient and do your homework first. Like he said, you need to find out your axle gear ratio. And you better have a V8, and not a 4.3L engine.

If the ratio is too small, then your poor torque converter is just going to be slipping and slipping. Sure a cooler will help keep the temps down, but you still won't be going anywhere.

Huge wheels are also harder on suspension, steering, CV joints (if you have them), bearings etc. Hopefully those were also reinforced with the lift kit.

 

yes it has a v8. It has the 5.7 vortec. I'll see if I can figure out the ratio then. From what I can see it looks like they were reinforced.

 

all you have to do is look at the RPO sticker on the door. Look for a code that looks like GU8. Use it to look up your axle.
