Default Tire Damage

Pulled my wheel pants to check brakes and tire pressures before an extended cross country and found this gouge and crack in the right main. The tire is a Vans supplied Air Hawk 5.00x5 that came with the kit about 17 years ago. Its got 140 hours and approximately 360 landings on it. All on paved runways. I run them at 36 psi.



1. I'm inclined to replace it before the next flight. What say you?
2. Is it best to replace both tires at the same time?
3. I've had zero problems with leakage so would it work to reuse the tubes?

If the tear is outward of the corded portion of the tire, it should be fine. The tire has a key thickness (includes the nylon or steel cording embedded within it) that it needs to support air pressure and vehicle weight. There is then a thick area on the outward surface that is designed to wear away without compromising strength.

From the pic it looks like you are outboard of the core area. However, it is hard to tell from a pic. If you can't see any cording, you are probably ok. I would definately replace a 17 year old tube. Rubber is an age limited item.

Any sidewall damage is not acceptable. Replace the tire.

17 years!
You have got to be kidding!
I donít think they owe you anything and should be replaced based on their age!

+1. Unless they were stored in a dark, oxygen free environment.

Default Tires

The cost of a tire is not worth the hassle of repairing the wheel pant if it throws a piece of tread. I have a self imposed life limit of 10 years on rubber parts. I would change all tires and tubes that are old.

Thanks everyone. New tires and tubes are on their way from ACS. I'm staying with Air Hawks and leakguard tubes since it seems the first set of these have gone above and beyond the call of duty.

I once downloaded the hundred-odd page tire guide from Michelin, and Goodyear IIRC, they outline very specific parameters on 'acceptable' tire damage which is good reading, whether you apply it or not. Half the guide is about 'big boy' tires, but everything that applies to cord, tread, tubes etc. is good info.
give it a read some winter day!
