need help selecting right tireSIZE16

first off let me say that im a bigger than your average bear when it comes to being a road cyclist so i understand that wearable items ( tires, chains cranks etc) will wear alittle more quickly than normal but here is my question i seem to have a problem with the rear tires in that they seem to split or tear on the sidewall... the tires will only have between 100-600 miles on them. please help by telling me what tires would probably suit me best ,,, the foldable tires seem to do worse for me than anything ,,, my weight stays between 250-255 and i ride a trek 2300 slr 63cm if this will help

Chose the "right" tire, what are you running for a "left" tire. Yuk. Yuk.

At your weight, you should be on at least 25mm tires, and consider 28s. Sidewall tears are either from some sort of impact (clipping stones) or abrasion. Also, cheap tires may have this problem at high pressures, but not brand name tires. You shouldn't be having this kind of problem at all, let alone at such low mileage. What brand/model and size of tire have you been running, pressure, etc?

sorry should have been alittle more specific ,,, the bike came with bontrager race xlite ,,, the rear tire lasted about 500 miles ,,, i still have the front tire after about 2000 miles ,,, i have had michelin pro, continental ultra 2000 which actually did ok i had one that lasted about 600 miles ,,,, i have gone through about 6 rear tires in 2000 miles ... i dont mind having a larger tire if it will not affect the bike itself or the handling ,,, any insights would be helpful... these are all 700x23c psi ranged from 115 to 125 ,,, by the way i do get the joke now:)
Conti tires in the 700x25 would be good for you. (nm)gogene

5 or 6 hundred miles is abismal tire wear.Spoke Wrench

Since the tires appear to be wearing out at the sidewalls, I'd say that the combination of tire size and air pressure is inadequate for your weight. I suspect that what is happening is your rear tire is "squishing" too much. This allows the relatively fragile sidewall to come into contact with the road. A larger section tire with the same air pressure is going to "squish" less and ride on the tread rubber rather than the sidewall.

My wife and I ride a tandem and together we significantly outweigh you. We use Specialized Armadillo 700 X 26mm tires on the tandem. I run them at 120psi which is 5psi below their maximum rated pressure. We have had zero tire problems and zero flats and lots more than 600 miles on these tires.

Another tandem team, who are very close friends and whom I trust, uses Continental Gator Skin Ultras. I'm not sure of the size, but I assume they are in the 26 to 27mm range.

I think that the Armadillos are all-but bulletproof relative to puncture protection, but the Gator Skins will have better performance characteristics relative to handling and speed.

I weigh ~195 and have been having extremely good luck with these tires, in both dry and wet conditions, and in terms of durability. After around 1,000 miles, the rear is just starting to flatten out, but not badly at all. I'd strongly consider them.

Even better--I've seen these all over the place in 23 (Lickton's has the best price on these) but I understand that they are also available in a 25. If you can get a pair of those (or just one for the rear) you should be in great shape.

Your front tire will last forever, or nearly so. Replace it every 1,000 miles or when it looks cut up and you should be in pretty good shape.
Check your pressurejtolleson

the sidewall issue, combined with your weight, screams "low pressure" to me. Are you also getting pinch flats?

Get a 700 X 25 and keep 120 psi in it, check it EVERY ride. Michelin Axial Carbon, Conti Ultra 2000... both are good for combining some durability with good ride quality.
Also, make sure your brakes aren't rubbing the sidewall.js5280

That could cause this as well.
EXCELLENT POINT!Spoke Wrench

I overlooked that and I think it's the most likely possibility.
