I have 17" chrome bullitts on the front with Nitto NT450 255/50 tires. How would it look with 18" chrome deep dish bullitts on the back with 255/45 tires? Also I would have to go with the Nitto 555 tire since the NT450 isn't available in 18 inch. Would there be an issue with mixing threads?

 

Here's hawgman's sweet ride w/ DD18's and 17's. 235/55/17 on front, 305/45/18 on the rear

 

Or you could go with the Nitto 555 in 255/50/17 on the front with Nitto 555 in 255/45/18 or larger with the deepdish for the back, should look ok.

 

Well I was trying to avoid buying new tires for the front. I was wondering if there was an issue with mixing thread designs?

 

I wouldn't think that mixing tread designs would be a big deal... but I'm no expert. On lesser cars, I've had tire companies recommend to replace "just the rears" with completely different brands and treads - and I never had any problems. My concern would be the mis-matched look... but look to my name and take it for what it's worth.

 

It shouldn't cause any problems. You may want to run something with a bigger sidewall out back, like a 275 or 295/45/18. I think it would look goofy with a fatter tire sidewall up front.

 

I would think if your front and back tires are of the same tread and from the same maker that they would handle better than mismatched tires.

 

I wouldnt think it would be a major deal to have different tires, but I wouldnt, because I like the consistent, symmetric looks. Hawgman's ride is definately awesome looking.
