PATCH or REPLACE tire ????
I got a small nail in one of my rear Nitto NT-05's.
Is it safe to just patch the tire?
They have 1/2 tread left and would hate having to buy new tires.
Plus, I'm guessing if I replace it, I need to replace both rears to match it up.....true?
If I can patch, is it safe to road race it with a patch?
Thanks a bunch!

I did a full track day on a patched NT05 with no problems. However, I had it replaced as soon as I got back so I don't know how well a patch will hold up over lots of aggressive driving time.

I am no tire expert, but I always heard that it is never a "safe" or "good" idea to patch a high performance tire due to the patch causing the tire to lose its speed rating. I also have the same belief that you need to always replace tires in at least sets of two (2 front or 2 back), but even that is when the tread remaining / life of the "old" tires are not that bad. Never mix brands and tire treads either.
Just food for thought.

OTOH if the OP's not tracking and/or otheriwse driving the car at extreme speed? Patching's fine, he'll be good to go.

your tires are junk...I will give you $ 100 to ship them both to me.
Seriously, just patch/plug it and you will be fine. I have done plenty of track events with many different tires w/patches/plugs. I have chorded tires and the plugs are down to the bone...the plug/patch was welded to the inside of the tire due to heat.
...but again, I will give you $ 100 delivered to KS if you think they are junk...gladly.

I've never had a problem with patched tires. Got a screw in one of my Invos the day after I put them on the car, plugged it with my roadside kit and took it to have it patched. Ran for a couple of days with no loss of pressure from the plug kit, but patched it anyway to be 100% sure. I had the roadhazard warranty, so it was no charge to patch it.

Small nail hole...like everyone else said, plug and patch. But be carefull if it is near the sidewall. I've tracked my first Z06 with 2 nail holes plugged and patched in the same rear tire.

That is generally true. Some tires such as the GY EMTs can be patched and maintain their speed rating if the proper procedure is followed. I imagine plugging the tire yourself doesn't follow the procedure defined by the manufacturer. However, if you lose the speed rating on a Z-- Y rated tire and you are doing nothing but highway driving that probably isn't an issue. There are thousands of L (75 mph) rated tires running around our highways at this moment so I doubt running a Z--Y tire that has its rating degraded on a Vette is a real issue. At the worst it might drop its rating to 75 mph. How many trucks and SUVs have you seen tooling along at speeds above that with L rated tires?
Will a patched Z rated tire hold up to the speeds achieved at most track events? Probably since the speeds rarely get over 130 on most tracks. Speeds will reach 150 to 160 on the longer ones but can a plugged Z--Y rated tire handle those speeds since it was designed for 186 mph. Maybe, maybe not. It all depends on how much the speed rating is degraded and that is an unknown.

I have been on track over 150mph with the patch and plugged OEM rear tire. After watching my highly experience tire shop make the repair I wasn't concerned at all. There is no way that small nail hole was going to hurt the tire, and no way in hell that repair was coming apart.
