I took out your 1st thread ok?If I'm going to replace my back tires, and I have to, considering I lost one last night, is there anything I should keep in mind? Do you lose much MPG going with all-season back there?
I use Michelin AT/2 tires because of the decreased rolling resistance, and because they have more tread to begin with than other "e" rated tires. I'm a tread junky.
Many people rotate tires left-to-right and not front-to-back, and just replace them in pairs as needed.
Michelin's LTX tires come in Mud'n'Snow, All-Season, and All-Terrain. My first set was AS, the second two sets where MS and the most recent two sets are AT. Not a lot of difference between the MS and the AS tires. Same tread depth, but slight difference in tread pattern. The AT (AT/2) tires have a more aggressive tread pattern, and deeper tread to start with.So what about all-season?
Michelin tires are engineer for reduced rolling resistance yet keeping or improving the traction and stopping distance of their tires, relative to previous Michelin tires and to other tires on the market. If the only factor to rolling resistance was the amount of rubber on the road, then you'd be right about less rolling resistance equating reduced traction. But that's not the only or even primary factor involved. Sidewall construction and the composition of the rubber are the important ones. The specs for traction and stopping distance for Michelin tires are equal to or better than that of over tires. But the reduced rolling resistance introduces a fuel economy savings that will more than pay for the tires over their lifetime (especially if you keep them properly inflated, either because you're anal about tire pressure, or because you use nitrogen, or both).And doesn't less rolling resistance automatically mean less traction? I can't see how it couldn't.
Turtle. Are you using Nitrogen? We have a Ford dealer in our area that has it available but no others. You can't mix air w/Nitrogen so what do you do on the road if you need some/?
Took the words right out of my fingers. The air we breathe is already roughly 78% nitrogen, 21% oxygen, and smaller percentages of argon, carbon dioxide and tiny amounts of other gases. So when you fill your tires with air, you're putting 78% nitrogen and 21% air in them, anyway. When you have them filled with nitrogen, they use about 95% nitrogen, as a higher percentage only costs more and provides no additional benefit, and less than 90% and you don't get the benefits at all.Of course you can.
