Punctured tire replacement - can I replace only 1 tire - is it safe to replace the PUNCTURED tire only?

My 2005 Honda Pilot rear left tire was punctured near the threshhold (ie - sidewall), but still usable. Thus the tire dealer patched it only. Should I replace that punctured tire only? Or should I replace the 2 tires on the same axle? Or even buy a whole set of 4 tires?

I'm concerned about safety, and thus your best advice is very appreciated.

As long as you put the same (or very similar spec) tire on the axle, and the other tire is still good, then you only need to replace the damaged one. If the tire wear is slightly different it's not a problem.

Or, have a look at all the tires, it's possible that one of the front ones are worn more. So it may be sensible to rotate them and put two good, but 1/2 worn tires on the front, and then put 2 brand new ones on the back.

If it was patched it is safe to drive on. It is important to maintain a set of 4 tires because if the traction of one tire is greater or less than the traction of the others it can cause the vehicle to behave unpredictably with regards to handling, acceleration, and braking, especially in poor weather If you personally would feel more comfortable with a new tire then you may replace 2 making sure they are on the same "axle". However your vehicle does have 4 wheel drive so it would be recommended that you replace the entire set of tires to maintain even traction.

What you do is up to you. But it may make more financial sense to keep the patched tire until you can justify acquiring a new set.

In most all instances it is best to replace tires in pairs, if not in sets. However, you would be safe to replace a single tire if the matching tire on the same axle still has at least 8/32 of tread remaining. If you do replace just one it would be best to stick with the same tire brand and model with the same load index and speed rating.
