I have 19" rays and have a set of brand new tires laying around from my other car I sold.

Will this tire size work on my 05 6mt coupe with 19" rays with stock height.

I plan on adding wheel spacers in the future only

Front: 235/35/ZR19
Rear: 245/30/ZR19

 

Yes, those sizes will work fine....Gary

 

will the ride be rough since OEM spec is 40 series tires.

I prefer ride comfort over performance

thx for your help.

 

The ride will be rough, especially with the 245/30s out back. And you will have massive wheel gap if you aren't dropped so be ready for that. If it were me I'd get new tires in the stock configuration of 225/40 and 245/40 for the Rays.

 

Both tires listed have a smaller rolling diameter than stock.

The front is a little small, but the rear will not look right. 245/30's on OEM 19's in the rear will look small compared to the OEM 245/40's. I tried 245/35's and it didn't look right. At the minimun, get 245/40's. You'll regret the look of 245/30's.

Speedo will be slightly off too.

 

what about

225/35/19 front

245/35/19 rear

?

 

You could easily run 245X35s on all four corners, I did on my Z it's whole life....125K miles.

were you dropped?

how was ride quality?

 

She was a '92 300ZXTT MT dropped one inch all the way around with almost the same suspension I have on my G....Sways/End links/Bilsteins/Michelins and a HKS exhaust with dual K&N filters chargers. The ride was perfect and she could out corner my wife's Vette. She's missed....Gary
