I'm thinking of getting wider tires but not sure what sizes will and won't fit

 

What's your budget, wheel size and weather?

 

I would start with your wheels that are currently on your car. I'm good, but i for some odd reason don't have the info I need.

 

It has 225/45R18 front and 245/45R18 rear, just kinda pricing around, and hot summer to cold winter but, NO snow driving

 

I’m guessing your car is equipped with stock 8x18” wheels. If that is the case, you are limited to 245mm wide tires.

One change you might consider if you keep the stock 8” wide wheels is mounting 245/40-18” up front. That provides better grip on the front and reduces understeer with 245/45-18 on the rear wheels.

If you want wider tires, you need to purchase wider wheels. --Spike

 

That I know, I was wanting to know how wide of wheels (rims and tires) I can put my car.

 

https://my350z.com/forum/wheels-and-...es-thread.html good place to look.

 

Ok and Sorry…. I missed that completely.

You can mount a plethora of wheels and tires on the 350z. That certainly is a feature making the 350z so much fun.

The easy sizes are 245 front and 275 rear. This size provides ideal handling for your 350z. That tire size dictates ideal wheels are 8.5” front and 9.5” wide rear.

I was told by a tire and wheel expert I could do 295 front and 325 rear or 10" front and 12" rear

 

You can get wider up front,just depends on the setup. Then wheels are one thing, tires different.wheels get refuted to in inches ie 10 inch front, also useless without offset listed. Tires are always metric unless you talking about trucks, they still have inch sizes at times

 

Lots of the rims choices I've looked at have offset listed

 

I’m not sure what you are asking?

The best result comes from a selection of tire size, wheel size, and wheel offset. You can search on this site for all that information as well as seeing the installed setups.
