Setup Options
The car needs new shoes so I am about to the pull the trigger on a set of 19" M3 competition rims matte black from **********s for my E90.
The car has a H&R Sport Suspension springs Rims: Front: 19 x 8.5 ET35 Rear: 19 x 9.5 ET 35 http://www.**********s.com/M3-Compet...atte-Black.htm Just running through the probable tire configs: 1. Front: 225/35/19 Rear: 245/35/19 2. Front: 235/35/19 Rear: 255/35/19 3. Front: 235/35/19 Rear: 265/35/19 Please give me advice of the the best possible options. Lets be honest I am on a budget and dont need $400 tires. I live in SoCal so just thinking about running summer performance tires.

Our non-M speedos were calibrated for a more consistent diameter front and back, so putting 30-series tires in the rear makes more sense in order to make front and back diameters consistent. Best bet would be to run the following to ensure front and back wheel diameters are the same: 225/35/19F, 265/30/19R or 235/35/19F, 275/30/19R Both specs have less than one percent difference in diameter between front and rear. To validate, try using the wheel dimension calculator above this Tire Rack-sponsored forum to determine if your speedo will read correctly at 60 mph.

flip4335 is correct as you will throw off your speedo with the setups that you've mentioned. I would recommend that you go with either setups below.
Front: 235/35/19 Rear: 265/30/19 or 275/30/19 Last edited by ModBargains.com; 04-01-2012 at 06:38 PM.. |
