For those of you with Toyo R888s, have you noticed your tires flat spotting after you leave the car sitting for a week or two?

This causes a vibration to occur when you first take the car out but goes away about 5 minutes later once the tires get warm. Is this common/normal with these tires?

Given that the only tires with a softer compound than those are full-on road race, or drag slicks of at least an 'intermediate compound', yes, I would expect them to flat spot when sitting for any period of time longer than a couple of days.

Remember those are 100 tread wear tires, the UN-streetable, Hoosier A/R 7s are 40 tread wear, and some other (even DOT) road race tires are 0 tread wear.

I plan to run these on my bird which will soon be retired to weekend/track duty. Will flat-spotting affect the life of the tire or will it be fine once they get up to temps?

I have been running R888's for 5 years now. Never had a flat spotting issue, even after sitting all winter long. What psi are you running?

I also had r888s for a good period of time and never suffered flat spots after sitting for weeks.

I love these tires and have never had an issue with them.

Texas heat and air pressure can cause it

Would more pressure like 35 psi help this issue?

dailydriver

You can try pumping them up to 40-45 psi right before you put it away for those 2 weeks, and then bleeding it back down when you take it out for it's 'exercise'. Then repeat.

Doesn't sound like there is an issue.

I drive mine every couple of weeks and never noticed it.

Unfortunately, my Z28 has been a garage queen for years. I try to take it out monthly, but that's hard to do during the winter months. I've been on 17's, 18's, and 19's and every tire I've had on that thing gets flat spots that takes 5-10 miles of driving to spin out. I've even bumped tire pressures up to 45 psi to try and help and it does slightly, but I've just had to learn to expect it and live with it...
