For some reason 235-50 are more expensive than 235-55 and 235-45, all 17 inch. Would it be ok to use 235-55 or 235-45 on stock 17 x 7 rim from 2003.5 6mt sedan? I am running 350z suspension so I'm lower by about 1". Also, anyone running ultrahigh performance all season tires? Any suggestions?

 

235/55 will put you above the 3% speedo rating you want to stay under. 235/50 would be a better choice. It will be almost at the exact same height as stock. They will fit a 7" wide rim but it will look buldged (over the side of the rim).

235/45 would worse than 235/55.

Even though you are lowered, I don't think you will have a problem clearing the suspension and the fenders with a 235. Should have more than enough clearance.

Also Discount Tire Direct will tell you alternative tire sizes if you enter your vehicle info.

 

go to tire rack.com and get Avon tech's around 110$ for tire(very resonable price IMO)...They are amazing and i have them in 235/50/17 on my stock rims. No complaints so far

 

Michellen Pilot Sport A/S ....... excellent tire .... a bit pricy

 

im running 235-50 on stock 17's

 

Dont cheap out.... and dont get 235-55... it will ruin the handling. If you cant get 235-50 on 17" wheels.... then you are better of sticking with the OEM size.... 215-55-17.... my favourite are Yokohama Avid VS4

 

i dun recommend 235 -50..i had it on mine..it jus felt wierd..couldn't corner as much as i did with stock tires..

 

I would at least go with a 225 if you can. Even the extra 10mm will help. Just make sure to keep the overall size as close to the stock as you can.
