Changing to 19" wheels but keeping the 18" RR

[Darren_Z]

Sorry if this has been done to death I just want to get this 100% correct before I make the purchase.

 

I'm about to buy some 19" wheels but want to keep the rolling radius of the Rays. The reason for this is I'm lowered on Eibach pro springs and don't have my arches rolled. My question is, what size of tyre profile would I need to give the same RR as the Rays and give no rubbing or TC issues?

 

If someone has 19s on Eibach pro springs could you please post/PM the tyre specs and some pics?

 

Any help on this is greatly appreciated!

Profile is the key

Darren, we don’t have any photos but we fitted a set of 19’s and Eibach springs a few months back on a 350z and the tyres were 245/35/19 F and 275/35/19 R as requested by our customer and used by many many others with no issues...

Thanks for the help Lexx and CS.

 

CS, this is exact answer I needed, thanks for that. I still have the quote you provided me for the grids, I will be in touch shortly.

You're very welcome...

Just to add that the RR itself isnt what would trigger the TC, its the difference between front and back
