I have got my mower handling pretty good, however, in order to do so I have to pump my right rear tire up to around 12 psi. In doing this, the 2 ply tire I am using "bows" up and I lose quite a little contact area of the tire.
Nearly all of last year, I was running a single flathead, and the tire bowing up didn't bother, but now I am going to run a Vanguard twin. With the extra power that this motor makes, I am sure that I will want the biggest contact patch that I can get.
Can I put a 4 ply tire on the right rear and run the same air pressure that I have been and not have the tire bow up? Or, can I run lower air pressure and rely on the extra stiffness of the 4 ply to carry me through the corner?
I don't want to change the handling of the mower, just want the tire to have a flat face.
