I never have worried about the interior of the tire. The exterior wears out much faster.Ruark wrote: ↑Tue Aug 17, 2021 10:55 amHuh? So, how many times have you had to replace a set of tires because they were "deteriorated from within"? How many times have you had to re-inflate your tires because the "smaller molecules seeped out of the tire"? I check my normal-air-filled tires at least once a week, and have to put air in them maybe every 6 months, if that often. Yeah, big deal, so what.LDB415 wrote: ↑Sun Aug 15, 2021 1:23 pm Oh, yeah, far drier than regular air so the tire compound and the wheel material are less contaminated and deteriorate far more slowly from within. Oh, yeah, larger molecules so seeping out through the tire is much slower meaning pressures stay up properly much longer. Oh, yeah, more temperature stable so the fluctuation in tire pressure from cold to hot is less keeping the tire closer to optimum pressure at all times. But yeah, big deal, so what. YMMV.
Maybe if we used nitrogen we wouldn't have to change the air pressure in the Winter when it gets cold, and again in the Spring when it heats up. I've bought tires at Costco with nitrogen and new cars with nitrogen. I used to be concerned about adding air at home, but I stopped that nonsense, and bring out the compressor whenever a tire has low pressure.
