Dinan, are lighter-Stronger and that = Dearer.
Dinan make the fronts in 9 inch so I run a 265/35/18 upfront and a 275/35/18 on the rear 9.5 inch.
Some guys run 275 upfront and 285 in the rear with the dinans but they can rub when you go that wide. I hate rubbing. This setup is good becasue, No rubbing, No Spacers, No Tramlinng. Just improved handling also due to reduced unsprung weight.
