Tyre size help

[natony]

I've just bought a set of 19" wheels but i can't find a definite answer to what size tyres i need.

 

The front wheels are : 8.5" wide with a 35 offset

and the rears are: 9.5 with a 40 offset

 

any help would be much appreciated

I have the following which are close to the stock diameters which you always try to achieve.

 

Front 19 x 8.5 +39 offset , 245/35

 

Rear 19 x 9.5 +37 offset, 275/30

pretty sure the set i have is 235/35/19 and 265/30/19

 

235/45/17 255/40/17 is stock if keeping the approx same widths then you can make a basic -5 on the profiles as you go to 18" diamter and then -5 again to 19"

eg 235-245/40/18 265-275/35/18

235-245/35/19 265-275/30/19
