I have the Nitto NT450 tires and I am happy with them but I am thinking of going with the 275-50/17 rears for alittle more width. Anyone running this combo? Pictures are always good!

Thanks for the pictures. They do stick outside of lower fender quite abit. Any problems with rock chips, etc?

Not with mine but I only drive her in the good weather.

I always thought that is was a bad thing to run different thread patterns on front and rear, but I guess if you aren't running them in wet weather it probably doesn't matter.

Dumb question. Does the speedometer and odometer go off the front or rear tires?

I would think it was the rears because think about when you are on a Dyno, The speedo moves while the front wheels do not.

Also when you are doin a burnout/brakestand the speedo will move while you are spinning your tires even if you are in one spot.

Thanks. You're right. I should have thought about it.
