Hi, I have a Suzuki Grand vitara with 235/70/16 wheels/tyres, I have bought some 17″ rims and 235/65/17 tyres, any idea of tyre pressure needed?

There is a chart for that right over your comment…

The percentage you have when you compare 2different sets of tires applies for everything.

You get 3% more, you need to ”times 1,03” everything thats depends on your total wheels diameter.
You see 100 on your speedo, you actually doing 103.

Fuel consumption is a bit more complicated, l/100km becomes this:

10 Liters ? Liters
on = on
103km 100km

(10×100)/103= 9,71

mpg becomes this:

20 x (1.03mpg), so
(20/1,03) x (1.03/1.03mpg), so
19.42 x 1mpg, so
19.42mpg

Your new tire is 2.7% bigger than the stock, and the limit is 3. For fuel consumption, generally speaking, the % of the new wheel total weight must be divided in 2 to get the effect on the fuel consumption.

So, if your new wheel is 20% heavier, you’ll need 10% more fuel for the same distance than the stock wheel.

Easy, 195mm width, 50% of the width gives the wall, 15” rim diameter. In a wheel total diameter you have walls and 1rim:

195mm 2×50% 15inches
195mm 100% 15”
195mm 195mm 15”

New tire:

195mm 2×60% 15inches
195mm 120% 15”
195mm 235mm 15”

235-195=40, so your new tire is 40mm bigger than the stock one.

But, the rule for bigger tires is max 3% bigger in total diameter, and your new tire is almost 7% bigger so I really don’t recommend it.

Hope it helps

You can but it will be awful and it will fuck the speedo. Plus, it is illegal to reduce total diameter of any wheel on a car. Maximum 3% in greater diameter, higher than the tire will rub somewhere somewhen.

Does this site have a version in inches instead of metric?
