315/70/17s too mich for 3.42s?

[llorracs93s10]

I've got a 90 rcsb silverado and it has the 5.7 . I was wondering if that tire is too much for the truck. I am not sure if the trans would hold out or not. I d not off road so it is more of a street only truck.

i wouldn't do it personally i think it would be way to much. if it were a 5-speed it wouldnt be bad because i ran 305-70-17s with no problem but that was a 5-speed

those tires with new tread are a hair over 34" tall that woundnt be an issue there are a few guys in my area running the equivelent of those but 16" not 17" and have no issues and one of the trucks has 3.42 gears with a/t

Really? The trans doesn't shift like crazy in and out of od? Any pictures of the setup?

You will want to run truck in drive for all driving except highway. I hated my 35 and 3.73 gears, od was just useless for most everyday driving. This is my experience with a 350 tbi 35s and 3.73 gears.

Ive been runnin 35x12.5x15s with 3.42 for 4 years, gone through 4 sets of spider gears and od isnt likin it much anymore but will still throw the truck sideways if i want to

I had 315 75 16 Mud Grapplers and not only did the tires suck, my truck was a disaster to drive. Lost power, trans acted up, G80 didn't work with them. Never again for me. And it was a dog at the lights.

I'm running 33's (285/75/16) with stock 3.73's & if it was any more tire I'd say it would need gears. I cant imagine how much it would suck to drive a truck with 3.42's & a bigger tire than I'm running now. I'd say it wont help your tranny live if thats a concern. I'd say a 3.73 would be more ideal & bigger than a 33" tire I'd honestly look at something in the 4.xx range to help the tranny & overall improve how the truck will drive.

Yeah I ran some 4.10's with 33's on my last work truck and it wasn't bad on the low end, it could still get up and move, I once drove a truck with 33's and 3.08's talk about a dog to drive!

ive driven heavy ass 36" tsl on 3.42 and ya it was slow to take off, and hills while cruising it kicked out of od alot, but i drove with the 36s and with 35s for almost a full year and did some towing with them even, not ideal but still did it

now i have 4.56 and 35s though....
