Recommendation for good tire shop in Orange County California?

[jagata]

I need to find a good tire shop that has experience with tire stretch and has maybe a touch less tire mount machine, I talked to America's tire aka Discount tire but they are to chicken due to liabilities they say. Going with 255/30/21 on a 10" or 10.5 wide rim.

I went 275 on a 10.5 originally and the stretch was huge. Not sure 255 on 10.5 would even work but It's probably been done before.

It always makes me laugh when I see comments like yours.

The rim width recommended for a 255/30 R21 is between 8.5-9.5". This is from the manufacturer of the tire you're trying to mount. When a company refuses to do it, it's probably because it's not safe to do. You say liability, in their eyes it's negligence.

Also, if that's the size your trying to put on a C7 S6, the load index (93XL) doesn't meet Audi's required weight carrying capacity for the car, even at maximum inflation.

I have the exact setup as you now, I just want a second set with that other setup to drive around a bit ( I drive to work and back) only and never gone over 45 mph so I know its not going to reach its limits. I been experimenting with rim and tire combos since 1986 and never had issues but rest assure I know and understand the ratings are for. I asked for tire shop referrals only.

check with evasive motorsports or supreme power, maybe they can help

[jagata]

Thank you, will google their info.

714 tires, they are in Westminster.

Thank you I will call them. Did some digging around on other threads and found a handful of members running on 255/30/21 with no reports of issues even a sponsor ran them with success.

You CANNOT run a 255/30-21...

Trust me, I found out the hard way after having several tires separate because they have too low of a load rating. 255/30-21 has a load rating of 93Y (Michelin told the the minimum rating for the car is 96Y. Here are pictures of my pilot super sports, I thought it was the tire, so I went with Pirelli's and had the same issues. All in all I had six tires fail (5 PSS and 1 Pirelli P-zero)

As someone in the tire industry for 18 years, I was only looking out for your safety. You don't have to push a tire to its limits for it to fail. Overloading and under inflation is the leading cause of tire failure. Mis-application would be another. I see hundreds of cars with the "stance" look. I'm sure some are on the forums saying they've never had issues.

You never have tire issues until you have your first one. Good luck.

I too assumed that running the 255/30-21 on a 9.5" wheel was fine, everyone was doing it. There was no 265/30-21 tire and 275s were too wide for my offset. Funny thing now is Michelin does not even make a PSS in 255/30-21.

When the first tire blew out, it was not too much of an inconvenience, I was driving and it was fairly easy to put the spare on, I assumed that it was from hitting a pothole or something on the freeway.

Second time it happened my wife was driving and she was out in the middle of nowhere. Roadside assistance came and put the spare on and she had to get a hotel room and wait a couple of days for another tire to get shipped to the tire shop.

The third time it happened it was in the back wheel and I pretty much ruled out hitting a bump in the road (that is three blown tires, plus the photos of the other three I posted that still held air).

I bought a set of Pirelli's instead of the PSS in the same size 255/30-21 ( Michelin had no 255 the 265 were on back order), we decided to trade the S6 in on a different car and took off the 21's, all four of the Pirelli's had the same separation at the bead as the Michelin photos I posted. I tried to get the tires replaced under road hazard warranty and it was denied because of the load rating was too low for the car.

To sum up the math, there was a total of six PSS purchased (three had blowouts while driving, three showed physical signs of failure) and four P-zero (one went flat, after 2 months all four showed physical signs of failure)

Damn, all those issues on a 9.5"???!!

It was more of a load issue rather than rim width issue.
