The same tires will go about 15 minutes before they get greasy. The tread wear of a 200 tire will have more grip but shorter tread wear then a 300 tire. A 300 tread wear thread will have less grip but more tread life then a tire with a 200. Most cases, a 200 tread wear will heat cycle faster then a 300 tread wear tire. |
Figured they were getting like that due to heat ...and the reason going to a 200 tire was to at least burn through the tread by the time they got hard ...hate to toss tires away with a lot of tread that’s hard as a rock ...makes me feel like I didn’t get the use of the tire
