Hello,
Time for a tire change. I live in central Arizona and never ride in the snow and hardly ever ride in the rain. I am looking for tires which grip the road well and stay grippy for at least 8000 miles. Tread life is not too important to me as I only ride 2000 miles/year or less. I had Toyo R888Rs on my viper and they really gripped the road unbelievably well. I have searched tire rack and found the following Toyo tires that will fit on my ride:

TOYO
PROXES T1R
185/55R15

TOYO
PROXES RA1
225/50ZR15

If I go with the T1Rs, will I need fender spacers and if so, will any decent tire shops be able to install them? Any thoughts or recommendations would be greatly appreciated. Thanks.
