quick tyre question

[GlennMR2]

what size tyres do you need on 19x9 fronts and 19x10 rears...can you tell me from the smallest size allowed to the biggest

For the 9x19 225/35/19 upto 265/30/19 and the 10x19 255/30/19 upto 295/30/19 These are not ideal sizes but gives you an idea of what will fit MIN and MAX.

 

Ideal fitments are 245/35/19 and 275/30/19

I'd also agree with Ibrar's ideal size reccommendations, as these sizes will help with maintaining a suitable rolling circumference. Although 19's wont do much for comfort or handling.

cool thanks for your replys . i take it that the same sizes for 18s but with 40 instead 0f 35/30

 

 

and how comes the backs are 30 and fronts are 35 ???

To maintain the rolling road diameter

[Lez]

The original stock wheels were 16s 8JJ 225/50/16 and 9JJ 245/45/16 with rolling diameter 631mm & 627mm respectively

 

However, from Aug94 the optional stock wheels were 17s 8JJ 235/45/17 and 9.5JJ 255/40/17 making the rolling diameters 643mm & 636mm respectively.

 

Therefore best size for 18s are 235/40/18 = 645mm and 255/35/18 = 636mm

 

However the recommended deviation is 2.5% so the max oversize from the stock 17s is;

Front

245/45/17 = 652mm +1.4%

245/40/18 = 653mm +1.56%

245/35/19 = 654mm +1.71%

Rear

275/40/17 = 652mm +2.52%

275/35/18 = 650mm +2.2%

275/30/19 = 648mm +1.89%
