Performance difference between 235 or 225
(Grand Rapids mi)
I have a 2004 Jeep and i have 235/ 70 /16 tires on now, but on the door it says the jeep takes 225/75/16 . does it make a difference which i use and why?
At a first glance, when you compare tire sizes and see that if one of the first two numbers in the tire size increases, the other number in the new tire should decrease. If that happens, you are on the right track, but still need to check the exact values to see that the difference is acceptable.
In this case we are going in the right direction so when we do the exact calculations we discover there is a difference of just slightly more than 1% in total tire diameter so the difference in performance is practically insignificant.
The difference of 10 mm in width is also very slight. Some people believe that a wider tire provides a wider contact patch and therefore will provide more grip, but if the same tire pressure is used in both tires the narrower tire is likely to have a longer contact patch so that the actual area of the contact patch would be almost identical, since it is determined by the amount of air which is held within the tire.
