Storing a car

In an owner's manual (non Tiger) it suggested that when a car is stored for long periods that the tires should be inflated an additional 13-15 psi. This will help prevent the tire from developing flat spots. I should mention that this is advice is for a car with "run-flat" tires.
I've stored my Tiger for about 5 months per year for the past 20 years. I've never experienced a flattening problem. Has anyone ever heard of or tried the extra inflation advice?

1/2

lb per month is a rule of thumb I have heard as to pressure lost . I had also thought that radial tires would not get flat spots until I got my Tiger. The 18 plus yr old tires never warmed up enough to loose the bumpy ride. Yes, I know the caveat's of driving on 10+ old tires. I suppose if I was to store in Winter as you do in Vt. I'd put on stands and lower pressures just to limit sidewall cracking. Is there a run flat in the 13" or 14" size that you are using?
 
car on jackstands, but...

wheels off and stored horizontally in a bag and suspension then compressed back to normal ride with gorilla ramps or other...

unless we just want to move the concern from flat spotted tires to shocks/struts/suspension bushings...

Easier... get wheels and tires only used for storage period. Even 'donuts'. R/R with actual wheels and tires for use when driving season is back, or when you've returned from other vacation home. ;-)

Or pay Leno's guy or the neighbor kid to drive it once a month.

Good luck,

Flat Spots

I experienced the flat spots years ago with my benz, but they would round out when driven. Now I just add additional pressure when storing all the toys.

Recently, I have seen small ramps you roll up on so the tires sit in a valley to keep their shape.

I was resisting the urge to post but it's my style to drift o/t and off track at autocross...:)

I think of this pic whenever the topic is tires their age and care. Old tire blowout center divider ouch.
 
Now that's a flat spot!

Thanks for the responses. I will try adding pressure and see what happens. I've never had to store "run-flats" so don't know what to expect.

Don't forget about condensation of air as the tires cool to winter temps.
I live in MN and we get quite a temp swing from the highs of summer
(95-105F) and the lows of winter (-20 to -30F). This large temp swing catches many off guard regarding tire pressure. The tires actual volume plays into the exact ratio but basically figure a loss/gain of 1 psi for every 10*F change in temp with larger tires having the largest swing due to temp change.
So, if you fill the tires on a nice 80*F summer day before going on a cruise and then put the toy away for the winter, by the time Feb hits and the temps are possibly below zero the tire could be around 8-10 psi lower than when filled due simply to temp change. Now couple the normal loss of air pressure over time with the temp induced loss and tires can get pretty squishy in storage over the winter. This can cause flat spots.
 
My dad was sold a set of nylon ply tires that would develop a flat spot just sitting over night. We all looked like bobble-heads until tries warmed up on a drive. Needless to say he was rather PO'd about the deal.
 
Awwww crap. I took a lot of air out of my Toyo R88. I wanted to put the car on jack stands but my wife wanted to be able to easily have it pushed out of the garage if there was a fire.

So will see what sitting for 12 months with 20 psi does to them.

Actually your wife has been drag racing the Tiger on Friday & Saturday nights
we just didn't want to upset you too much.. The car looks good and your wife made me a great deal on your motor I traded straight across for my old forty over 289...she said you wouldn't know the difference......When do you come home ??? I need to know how much time I have for the switch...

Let's just say, you are lucky to be 7000+ miles away.:rolleyes: I have a nanny cam in the garage. Be home on 6 August, have the TKO in the garage please, I'll install.
 
OEM Specs

FYI:
Factory tire fills are in the 40+PSI range to avoid flat spotting. The dealers are tasked with reducing the air pressure before any test rides are taken.
(When they forget the customer is likely to complain about ride harshness...)
