Down here where I ride there are not that many twisties and curves, so most of my riding is while the bike is straight up. Also, while I am practicing wheelies and such other tricks the tire gets most of its wear in the center....which leads to the rear tire becoming square.

Do all of you have this same problem?

I think this is why my wheelies are starting to drift to the right.....

Can anything be done to help prevent or slow down this effect on the tire?

 

If you stop doing burnout and wheelies, I guarantee the tire will wear much slower. Or... - More turns? Maybe fast circles in an empty parking lot?

 

if you run low pressure it will ride on the sides of the tires

 

Just do some chainsaw burnouts and wear down the side. I dont know why that wouldnt work
