Hello , I'm looking for some advice on tire pressure for storage. I have 265/60 15 BFGs . Thoughts on storage pressure to avoid flat spots? Would 35 be ok? Thanks, Steve
Assuming they're on the car, car is on the ground? I'd go higher, like 40-45. If they're being stored off the car, let all the air out.
On the ground. I'll go with 40 and I use some high density foam pads as well. Seems to help. Thanks, Steve
Do radial tires really flat spot? Ive had tires on concrete for years and never had a problem. Even my Polyglas's after being dormant for over a year seemed fine
Don't some of you Northeners jack the car up for that and to "relax" the suspension? Just don't forget to change over to spring air next year!!:TU:
i currently run 31 lbs on 245r60x15 bgf t/a. for winter, i will increase that by only 2 or 3 lbs because i place one foot square 1/2" pieces of plywood under the tires. beneath that on the concrete floor, is a plastic sheet completely under the car. the plastic prevents any moisture wicking thru concrete and condensing on the undercarriage of the car. the wood keeps the cold concrete off the tires. radial tires seldom flat spot over a winter, not like nylon tires.
I think even when nylon tires flat spot, the flat spots go away after the tires heats up a bit on the road. Can anyone confirm this?
Never any problem with car sitting all winter on concrete with normal pressures with the usual TAs or before that some Goodyear Wingfoots.If there is any "flatspotting" it is gone within a couple of miles. Rod
Certain tires are more prone to flat spots than others. Michelin seems to be the worst. Most come out of it within a couple miles. I certainly would not rule out permanent damage, but it is not usually the case. There are 4 belts in most tires that are constantly flexing, stretching and contracting as the tire goes down the road and if the belts start to interfere with each other, you will get a flat/out of round condition. I periodically move my car a bit every few weeks, maybe a foot or so, and it seems to help. The older the tire is, the more likely it is to develop flat spots.
I researched this online before storing my mounted summer tires for my 98 Riviera, for the winter. The recommendations ranged from deflating as much as possible, to deflating to 50% of normal. Sites such as tirerack.com and others have a lot of info on the subject.
Gte a set of junk wheels/tires and take the good ones off. Problem solved. You can get a set at a yard for less than $100
Thump, thump, thump. Yes, it goes away after a mile or 2. I know first hand from driving my late Father's '40 Lincoln and '37 Cord. They had nylon cord tires that flat spotted after sitting. I haven't really driven it the past couple of years, but do know the Radial TA's on the '70 would flat spot after sitting an extended period of time.
