these tires are super swamper ssr's. i kinda think i know the answer but i'm hoping i'm wrong. first is a 35"x12.50"r15 that is actually 35.3" tall with 10.6" of tread. next is a 33"x14.50"r15 that is actually 33.5" tall with 12.4" of tread. so ones almost 2" taller and the other is almost 2" wider. i assume the 33 will weigh a lil more because of the extra tread... or maybe the lugs are jus spaced out that much more. i dunno'. this would be on a hp dana 30 front end. which would i most likely have more problems with, as far as wearing out parts and such? my guess is the wider tire will grab more and put more stress on the front end components. what i'm hoping for is that since the 2 would be very similair in weight that they would kinda be the same in comparison. would i be correct to assume this. what i'd like is the 33x14.50, its only a 1/2" shorter than my 35's but would slightly help with my gearing. and i'd have an even wider stance. ofcourse this is down the road as i jus bought my xterrains but its what i'd like to go wtih next. or as soon as i could get $$$. but not if it'll be too much for the front end. i wouldn't be jumping it or abusing the hell out of it. but i would use it offroad. rocks, mud, trails, whatever.
