Tire pressure on 275-40ZR-17 BFG KDWS

**kevakasper** · 02-01-2006, 04:35 AM

Hey, just bought a set of factory SS SLP 5 spoke 17 rims with a new set of BFG G Force KDWS 275 40 ZR 17's Rims are 17 X 9.5 all four. Question since my Z had 16's originally, what tire pressure should I be running front/rear.
I have read about some weird tire wear on the rear center if the tire pressure is not dead on. Will be rotating @ 3k to distribute wear.
Any suggestions????
Thanks KJK

I would run 30 psi in all 4 tires.

Thanks thats what the placard said for the 245 50's that were on the car, Thats what I put in them for now, thought I'd watch the wear. Wasn't sure what the SS had for the tire pressure recommendation.

I have the same tires. Just got them last month. I run 'em at 30 like the door placard says.

How do you like the BFG's? So far I'm impressed. Much better than the Dunlops that were on the Z when I bought it, I thought I had a bad wheel bearing, was the tires!

Great, had the factory Good Years on mine. Those were terrible, loose, real easy to spin, and had a terrible vibration. Balancing didn't help.

BFG's much smoother, great ride, great wet traction, and dry. . .they just hook and go! Plus, damn good price! $144 each at Discount Tire in Orlando! Lifetime rotation, balancing, road hazard, & replacement guarantee!

I'm happy!

I just bought mine from a guy on E Bay, Got 4 SLP Zr1 rims like new, actual GM production pieces, with 4 new BFG kdws supposedly had 1000 miles with lugs caps and center covers for $599.00! I priced the tires locally and would have spent that alone for the rubber! The tires still have the nibs on the tread! They were mounted and balanced too! I have had them up to triple digit speeds and so far awesome addition to the ride! Quiet, responsive, and they look a lot better than the factory 16"s!

I have a factory set of chrome 16 " z 28 rims with some Dunlop 245 50 r 16 rubber on them for sale!!!! They do good burn outs, not much good for much else. Measure about 5- 32, chrome is pitted in the pockets, and flaking on the inside of the rims. I was going to put winter tires on them but I think I will just dump them.

I have those tires and I run at 32 psi.

I run mine at 32 as well, seems to give the best overall ride on the highway/street during the cooler months. During the cold season 30 makes them feel to soft but during the hot summers I go back to 30.
