Title: tyre sizes
Post by: doog on 16 May 2009, 01:52:10

Is it possible to fit wider tyres to my existing rims
at present i have 225/55/16 tyres on the car and wondered if those wheels could take a wider tyre and if so how wide can i go?

it all depends on the j of the wheel

best thing to do is goto a tyre company and get there advice

but remember the wider the tyre the lower the profile to keep the rolling radius the same :y

unless you race, a wider tire will be useful for lightening your wallet..

although may stay nice on miggy , will consume more fuel and brake pads..and lessen the life of hydraulic steering pump..

Increasing the tyre width will not affect the rolling radius.

yes it will
if you have a 205/55r16 tyre and increase the tyre width to a 225/55r16
then the rolling radius will be different

the wider the tyre the lower the profile needed to keep the rolling radius the same

You're right Nick. The 55 part is a percentage of the tyre width so a 225/55 is 225mm wide tread and the profile is 55% of that or 123.75mm :y

I agree with you too!  :y  :y  :y
If you go up in width, the profile needs to go down!  :y

it all depends on the j of the wheel
with out seeing the wheel to measure the j then i cant tell you if they wider tyres will fit or not
going by memory i dont think they will fit
best thing to do is get yourself to a tyre shop and get them to measure the j and they will tell you if a wider tyre can go on or not :y

you for sure shouldn't put 245/55/16. These ones have similar radious: 225/55R16 - 235/50R16 - 245/45R16.
