Okay so currently on my 350z the previous owner had 19s on it. The rims are trashed and have a thin layer of plasti dip. So I need new rims he was running 255/35 and 275/35 which I’m a fan of. I just don’t know what rim size I have to go with in order to be able to keep the tires. what size, width and offset should I look for when looking for rims?

 

19x9.5 F & 19x10.5 R (or 9.5 squared) with offset around +22 (or lower if you don't mind the possibility of rolling and sealing rear lips).

Be aware that most "less expensive" 19s will give you a weight penalty. Unless you opt for forged or at least roll forged construction, 19s will be boat anchors. FTR, I run all 19s but the specific sets I still have are all forged and weigh less (by a fair bit) with proper tires than the lightest OE wheels (except Track). My favorite S-Tunes are 20#/wheel. Heavier than forged 18s of course but featherweight for 19s.

 

any websites or places you recommend?

 

Wouldn't call it a recommendation because I've not used any of these places but they seem to get a lot of traffic...

https://www.aspiremotoring.com/ - Mostly rep wheels

https://www.fitmentindustries.com/ - Name wheels and reps (just went there to see what it was all about, pretty decent site)

tirerack.com - Biggest tire dealer on the web but their wheel selection is limited

 

appreciate you my guy in going to look into them
