With the high today of 70 degrees I drove the roadster to work,,,,after jumpin' it off and adding air to the slack rear tire. I'm kinda playin' around with the air and I have dropped the PSI in both the front and rear,,,,and the ride seems smoother,,,24 rear and 28 front What are you guys runnin',,,PSI wise? HRP
We don't have to worry about air pressure up here in the frozen north our tires are frozen solid who needs air!
I run 30 in the front and 27-8 in the rear. That is in bias ply 16" firestones from Coker. My rear springs are a tad too heavy so my rear could stand to come down a few pounds to compensate. Dam I am sweating today : it's a cozy 72 degrees in teh upstate of S.C. Later Shane T.
Radial or Bias? I only use the # for reference. Set them so they wear flat & even and feel good. On the roadster with bias tubeless we are running 18-20 front/16-18 rear, wears even & rides good. If you want to get realy **** get some kid's sidewalk chalk and make a band across the tread, drive in a strait line in a parkinglot and adjust till it wears evenly.
You KNOW I would have had mine out today ... but it is in sick bay ... So ... I rode the Harley instead I run 22 PSI in the front ( cold ) and 26 PSI in the rears ( cold ) ... but your rear tires are a little larger than the ones I run. The fenders are requiring professional help. but they are savable. Hammer and dolly ... dolly and Hammer ..
Don't apply to you, but I have heard of T-bucket guys running as low as 10 psi on those big *** rears trying to get a descent ride!!
Yah i woulda had mine out today too!! all I needed was for the weather 2 do a 60 Degree turn around and to install a backhoe on the 35 to tunnell my way outta the garage..Oh and I didn't ride the Harley today but i was over at a friends last saturday and we pushed his 2 Harley's around INSIDE his garage..nuff said you lucky ******s....
My A roadster with bias plys i run 18 all around.....Anything more than that and it gets choppy....In hot weather they'll grow a coupla lbs. on a drive
i run 18 in my fronts and 16 in my rears in my 27 T. I did alot of playing around with pressure before i got a decent ride. It all depends on the weight and suspension in your car...
At the risk of being off-topic, and not knowing your car, I'd wonder if the lower pressure is safe - that's how the Ford/Firestone mess got started. You obviously have a lighter weight car than a Explorer, it is interesting to see what would happen doing this. I like that chalk idea, never thought of that one! This is one of those threads I'll watch and maybe learn something!
As evidenced by the firestone/explorer fiasco a few years back, running low pressures for a cruiser is fine, but if you're doing a road trip, pump em up into the 30s to prevent heat buildup from low pressure.
YEP lower is better until sidewalls bulge too much. Manufacturer recommendations are always too high for me. I judge by the amount of flat contact at bottom of tire with floor.. Different for around town than for freeway speed on long trips. And it makes the car lower!
