They are vulcanized rubber. If they turn green, hit them with a 600 then buff. Wipe them with some obsidian oil, and they’ll be good for another 2000 miles.
New tires it is, then. Keep your eyes peeled for a sale. Tires are ‘spensive ?My Dutch brother-in-law is an engineer at heart, and he had the following advice on aging tires, that is of interest:
Tires last about 5 or 6 years, worn or or not. This has to do with rubber disintegrating over time and becoming less safe. So even if you have enough profile it's probably time to swap all of them. My friend Kees (Case), who researches these things and is a handy mechanic himself, always advised me. I think in Holland it may even be mandatory, just like winter tires are mandatory there.
End quote. He just did a home engineering job on their garage that had taken to leaning to one side, jacked it back upright and installed structural timbers to keep it in place. A carpenter who worked with him on some back porch steps called him "the engineer."
Nothing imaginary there. Tires are your connection to the road. They can make a huge difference in ride quality and handling characteristics.I did the deed and bought four new Michelin tires, discounted and with one tire at only $17 -- still pricey but about as good as I could do here. What I didn't expect was the ride. I always thought the comparative feel of different tires was in the mind of the driver, but the difference is immediately noticeable. Supposedly the Bridgestones that were original, and these were supposed to be comparable. Their grip on the road, their quietness, and their added cushioning of the ride are tangible and unmistakable. I'm glad I was able to spend the extra. These should do well for another seven years, with hoped-for on-the-road luck.
Reminds me of the awesome Bajaj scooters we had - Bajaj used to make Vespa in India and then kept on making the same style mono body scooters under their own name. They came with Nylgrip tires. You can guess what they were made of. Perfect hard-wearing tires for India but definitely not for moving at any speed on US roads. They were quickly replaced as well.Might just have been made of nylon for all the grip they offered.
Another thing many don't do, often because they don't know, is keeping up with the tire pressure. Also knowing how to find the correct pressure. My former father-in-law (MIL divorced) always inflated the tires to the number on the side of the tires. (If you're wondering, don't do that, look for the proper pressures on the sticker in your car.)Batteries and tires people skip on. 5 years, replace them, not worth the chance, I ran Cooper tires on my trucks, Michlen on my wife’s car, UV kills them. You may have good tread left, but the sidewall strength is gone. Replace them.
Could be worse, my car chews through $250/each tires in 15-20,000 miles...unless I'm having fun and then it's less, much less.I’ll be finding out how long they last. After traveling 800-1000 miles per week for the last 8 months, my tires now have 32k miles. I haven’t driven the Suby since last Friday when I retired.
Why such short life? Soft compound or is the geometry just hard on tires?Could be worse, my car chews through $250/each tires in 15-20,000 miles...unless I'm having fun and then it's less, much less.
