Tire Repair Question
 

I had to have one of my Potenza 050's repaired, only 5800 miles. I would like some experienced input on the integrity of the tire, for high speed driving, after a repair.
Thanks,

A lot depends on the location, type, and size of puncture. If you plan on doing much high-speed driving or hard cornering at speed, I'd go ahead an replace it. For a DD that doesn't get much over 70 MPH for very long, you should be OK. YMMV

it depends on the tire manufacturer. some brands say their tire is still good to go for their original speed rating. others are not. bridgestone voids their speed rating after a repair is done.

One drop in speed rating

I am curious where this info comes from. Your opinion? Experience? Tire Experts? This is a serious safety issue. As South Ark mentioned , this ain't a DD. I drive to enjoy.
I really appreciate all.

There are 2 types of repairs as we all know the plug type and the patch type.

I would not be pushing a cars limit on a plug type fix as there has been cases they failed.

For a dd no high speed driving? its Okay it'll get the job done

The other type patch will hold BUT depending on how big the hole was to patch it in the first place, say a good size screw/small bolt? not good But a small nail? Not really a problem.

But ultimately its up to you to use your best judgement.


EDIT: Of course this does not apply if the tire has damage in an unsafe location like near the sidewall or off the thread.

Tire Rack Info
 

Well, tire racks info on repairs & speed ratings popped up, some how. So thanks for that link. Pretty much says it all. Bridgestone (and others) void the speed rating, Michelin (and others) maintain the speed rating. And like kenchen said, some lower the rating to "H".
With this help, I feel comfortable up to XXX mph, but will not push too much. Also I'll consider Michelin for replacement.
Thanks
Edit: Repairs MUST be done in accordance with Rubber Manufacturers Association high standards.

i read that some time ago i think on tirerack.

but all damages are different so keep that in mind. a 1/4" puncture is not the same as a 1/8" puncture, location, who fixed it, materials used, etc.

if you're worried, i suggest you buy a new tire.

im fine with both patch and plugs in my tires depending on where and how big the puncture was, dd or not. a lot of folks say plugs are crap. i dont think so. ive fixed plenty of punctures using plugs from the outside and no issue.. 2yrs ago i fixed a puncture on my dd's tire in 11F temps... no issue even today. still riding on them.

Replacement
 

I'll go to Discount and check on this. The$e things never happen at a good time. Christmas just over .....and our Granddaughter needs air fare to Europe in May.....
Again thanks...

IMNSHO, I don't think that just because Michelin doesn't de-rate a repaired tire it means that you shouldn't either. Especially if you are driving at high speed for extended periods or stressing the tires (it sounds like you do both). Michelin makes some good tires but they are susceptible to the same damage as any other tire. Don't take chances on critical systems such as brakes, tires, steering, &c.

New Tire
 

Yeah, I going to get a new tire, before I do any serious driving.
Thanks,
