i guess i never had the T1-S long enough to where they got loud. i sold my set at about 10k miles. they were the quietest tire ive driven. other tires ive had are re-92, re-040, es100, and azenis sports.
245-35 and 225-40 have the same sidewall height (off by 0.1 inch) so the comfort between the two sizes, given the same tire, is essentially the same.
