Is it possible to change tyre size?

[n30_mkii]

I have a Honda CR-V which currently has the following tyre dimensions

225/60 R18

There are only a few different tyres in this specific size and the ones I'm after are out of stock everywhere at the moment. Is it possible to use a slightly different tyre dimension or is that a big no no?

Thanks

As long as you keep the same specification or better (ie speed rating etc.) then the only real issue is throwing the speedo out.


60 profile seems pretty hefty for an 18inch rim, is that standard for that car?

Edit, ahh the CRV is the 4x4 one, I was thinking of the CRX, lol! I would go with a 50 or 55 profile, 45 I think may feel a bit hard and crashy, especially for a car of that type.

Ok so next question is it legal to have different profiles front/back? I'm only looking at replacing the two fronts at this point in time

Legal but generally a very bad idea on a 4x4.

Thats what I was thinking tbh. Looks like I will see what else is in stock and bite the bullet then

if you want cheap tyres buy a small car

The cost doesn't bother me its the reviews of the ones in stock are poor and the ones with good reviews are oos everywhere!

Try some online fitting services? you can usually find exactly what you want for a good/best price if you shop around a little.

That's what I was going to do but the two tyres I'm after are OOS at all the usual suspects. Thanks for the help though folks

205/65 would be a better, if you go down in width you go up in aspect ratio
odd size by the way

Thank god somebody mentioned this.

As mentioned, the sidewall number is the % of the tread width.

225/60 = 135mm sidewall
205/65 = 133.25mm sidewall

All possible sizes that will have a negligible difference to speedo accuracy.

Anyone know of its possible to go down to 195 from 205 on the Type R standard 17" alloys?

Before changing tyre sizes its a good idea to phone your insurance company and check if they are ok with it. When I moved from runflats to non runflats on my car they said that was fine as long as I didn't change the size or rating of the tyre.

Shocking advice, he has a 4x4 with high profile wheels and you suggest a 45 profile on the same tyre width!?

More than likely, But why would you want to? very limited choice of tyres in 195 17's.

 

[Dave85]

yeh was just curious as to what was possible
