275/55r20 seems to be 3% bigger and 10lbs heavier than 255/55r20. How this affects handling, acceleration, various car sensors? I see quite few people using 275 without issues (so far) but it doesn't mean everything is right. I am just trying to avoid costly mistake.
not all tires weigh the same, not sure the general statement of 10lbs is applicable.
I was comparing specifically stock Goodyear F1 255/55r20 (37lbs) with Duratracs 275/55r20 (47lbs). I agree that other tires will vary but generally will be heavier.
