Soooooo

I can pick up a nice set of BFGoodrich Mud Terrains for about 30 percent off ticketed price thanks to a buddy whos working at a tire store that's going under.


I can pick up either 33's or 35's. The stock gearing is set for the 235's and right now I'm running 31 BFG's.

I got no issues with clearance because my truck's already lifted.

Should I regear it to a better ratio or can I say screw it?

And what's the worst that could happen?

You will lose power, speedometer will be off, wear out the engine and drivetrain parts faster. IMO.
Plenty of links concerning all this if searched for.

I've got the same question. I recently had to buy new tires and got a good deal on some BFG AT/ T/A KO 33x12.50. I had to install a lift so the front tires would not rub while turning. I had a 3" body lift I picked up a while back and installed it. Now I'm left with the question of regearing. I'm running the OEM 3.54 setup and looking to go with a 4.10. I haven't got to far along in my rig build so basically everything is still stock.
How do I recalibrate the speedo for the bigger tires?
On the powerhouse end I'm looking at putting on a set of shorties and Edelbrock Performer Heads.

I'm running 35s with 4.56 gears and I love it. Huge differencethen when it had 35s and stock gears. I can still cruise 70 on the freeway at about 2000 rpms. I would say definatly re gear it. My rig goes so many more places now that I did the gears.
