Im looking to get new tires.
Currently Im have have the stock rims which i believe is 17x8, with Pirelli P Zero Nero 235/55ZR17 98W.
I want to get something wider and with more grip.
I have been looking into the Nitto NT555 Tire 255/50R17 101W.

My question is will be able to fit a 255/50 in a 8 inch rim safely.
Or should i go with and 235 front and 255 rear.

I think im ok with the load index.

This is just my summer car and I store it over the winter, but i will be driving it everyday during the summer. So if anyone had trouble with this tire please comment...
or any other tire suggestions

Thanks everyone!

Based on your tire size, it looks like you are talking about the 2005+ mustang. Try posting in the 05+ forums and I suspect you will get plenty of input. The 94-04 which this section discusses uses a shorter wheel and tire combination.

Another resource would be the specifications available for every tire on tirerack.com. Find a tire and look at the specs to see if 8" wide wheel is within the suggested range. I suspect it will be, but you'll need to look at your car or ask the 05+ forum if the tire clears the suspension, ect.
