ive got a way to get LOTS of 120 and 160 size tires locally and am wondering if this would be ok option with the 400s. I know it nots the stock size but is there a problem if you match the front and rear in size increase? how much is the profile affected if these are "sport" type tires?

ive seen threads about 160s and 120s but never about both at the same time so figured it cant hurt to ask.

i know another newb question but the only way im learning is bc of guys like you!

I've got no first hand knowledge of it but I'll play devil's advocate just for shits and giggles... over the years (I'm fairly sure I've read every post in this forum since Sept '03), I know we've had members try both (not at the same time that I'm aware of, tho) and no one has come back to us and said that they had a hideous or awful experience. In fact, I think most have come back and said that they really didn't notice much difference.

Having said that, I have a lot of respect for what Jay has to say (so long as he's not lecturing on grammar or spelling). If he says don't do it, I probably wouldn't.

When you move up a size in the width you kind of "squeeze" the tire up from the rim since it isn't also getting wider. Sometimes you can compensate by dropping the sidewall percentage to a 60, but then the tread will "creep" down further and you'll still have an odd profile. Better, but not ideal.

Will you notice? Who knows, what you will notice is new rubber. I went from dry-rotted tires with the front in entirely the wrong size (110/80/17) to primo rubber in the correct size and the change was dramatic. Would it have made a difference if I had upsized? Yes, I would have still had fresher rubber than the crap that was on there initially. Would it have mattered to me? Probably not since this was my first "fresh" set on the bike.

Tires are kind of a consumable good, it's not like they'll last forever and you're stuck with them. If you can score a screaming deal on them locally, give it a shot. In worst case scenario, you'll have to get a new set eventually anyway. YRMV, and since it's winter, why not just save the money since I doubt you'll be riding in Dec. in Kansas anyway.
