Hi...

I got my 18" rims with 225/40/18 my question is can I replace it with 235/40/18..cause I am getting a great deal on the tires that I can buy now and store it for future.....

What r the effects any(pro's or con's) for changing it form 225 to 235 and in the rear I am running 255/35/18

thanx

your tire will be wider, actually it might have a positive affect

The first number (225 or 235) represents the cross sectional width of the tire at its widest point in millimeters. The second number (40) is the tire's aspect ratio as a percentage. For instance, a 40-series tire has a sidewall height that is 40% of the cross sectional width. In the case of 225, the sidewall height would be 40% x 225mm = 90mm. A 235-40-series tire would have a sidewall height of 94mm, which translate into an overall diameter gain of 8mm or about 3/10 of an inch.

When you go to a larger diameter tire, it will affect your speedometer and gear ratio somewhat. The gearing would be slightly taller. This is why most people go to a lower aspect ratio when increasing the cross section width, especially if going +1 on the wheel size.

the 235s will be fine ... and it gives u a little more protection from wheel damage from potholes, bumps, etc.
