What's the safety point (speed rating) on a V rated tire if you have to have a patch for an extremely slow leak caused be a very small flat nail?
Doesn't anybody have an answer for me. I need to know how fast I can go still without having any safety issues.
The speed rating is for a unmolested factory tire. A small nail hole with a patch inside the tire should not be an issue for most driving.
If you are driving over 120 MPH for long periods you might consider a new tire. Driving 80 MPH on the interstate for long periods should not cause too much concern.
Enjoy life- you only get one!!
So long as it is repaired correctly you shouldnt have any issues unless you are pushing it to the max. In the military we repaired our own tires . First we plugged the hole , then we ground out an area so the patch would sit almost flush inside it. Granted these werent high speed tires , but we have had the Hummers well over 80 MPH with no issues.
Since I have a V6 I dont have the issues with top speed you do , lol.

Ok, so you think I'm safe for stretches between 70 & 90 with an occasional burst to 110ish on occasion (til I replace). The tire shop guy told me because it is a V rated tire he did not drill out the hole to save some of the speed rating. He told me not to go over 140 (not a problem with a stock RT anyway).
He loves ya man .... now give him a Budweiser !
With a properly repaired tire (at a good tireshop), I don't think you will have a problem 70-90 with a blast to 110 once in awhile.
The risk *IS* higher for a blowout, can't deny that.... but I, Personally, would have no problem with it in my ride.

The actual rule of thumb is, you loose 1 speed rating for every repair up to 2, after the second repair, it drops to a S speed rating(102 mph) so if you have a V rated tire, it is now an H(130 mph)...and that's only if the tire was repaired using tire industry standards...
