The tires on my rider have the dry rot, they are Carlisle 20x10.00-8 2 ply.

I would like a little more stability on banks, maybe a thicker sidewall would help a bit, so may go with a 4 ply.

Suggestions, thanks.

You can put tubes in them and get a few more years out of them, IF they're not rotted to the point of total deterioration.

I replaced the Carlisles on my Exmark with Kenda K500s for about half the cost of the original tires. Overall the tire performs well and they are 4-play which is a good choice if looked for something stronger/more durable. Dry rot may also be accelerated by extended UV exposure (storing outside) and not cleaning off your tires periodically (decomposing grass).

It pays to shop, I found prices fluctuate wildly, and I put tubes in ALL the tires, yes even a new tire, I got pissed off too many times over a flat tire, and decided the tubes were not as costly as the headaches !

Thanks guys for the links and advice. I see the 4 ply will take 22 psi instead of the squishy 12 psi 2 ply tire, so should be more stable on the grades:thumbsup:

Max pressure on the Carlisle tires is the same. You should go by the pressure recommend by the mower manufacturer, not the max pressure. Running at max psi will give a harsh ride and reduce traction.

The maximum tire pressure is going to be higher with a thicker sidewall as is the load capacity, but like Darryl said, the recommended PSI from the manufacturer will give the best ride/traction. Over-inflating the tires changes the shape of tire to be more rounded, reducing the tires contact patch. Also, the height at which you set your mower, and adjust to, is determined somewhat by tire pressure. That is why they recommend that you adjust all of your tires to the correct PSI prior to adjusting or leveling your deck.

All the Carlisle mower tires I see listed say they're 4 ply. It doesn't specify if that's the tread or sidewall though. I mow some pretty dicey slopes with mine and never had an issue with sidewall flex/instability.

Nothing wrong with the Carlisles, the Turf Saver http://www.carlisletirestore.com/trf_svr.htm is a standard tire for many riding mower manufacturers. I just thought there are better options, such as this Carlisle http://www.carlisletirestore.com/trf_mstr.htm or a Kenda as mentioned in above posts.
If I got the 4 ply and ran 15 psi and the ride was too harsh, I could let them down to 12.

O.K. maybe overkill and going too low on the air for that tire.
