Standard 17" Alloy tyre size
« on: 15 May 2012, 15:34:52 »
What is the maximum size of tyre I can put on my 17" Elite alloys?
I am looking for a Higher profile and Wider tyre.

What's the max people have put on these alloys?

I will be putting 265 40 17's on my rear wheels at some point in the future. I wouldn't bother going any wider on the fronts though.
235 45 is plenty on the front

The larger the sidewall, the sloppier it gets.
If anything, you want to decrease the sidewall height (along with the increased tread width) to improve the handling.

Don't make the common mistake of "over egging" the mixture either, because it's a fine line between improvement of handling and f**king it up altogether.

After a very interesting conversation over a curry on Saturday evening I'm not sure I agree... I'll grab the popcorn and await 2woody and his fantastic explanation of how tyres work :y

that's just the point no-one really knows how tyres work, not even the manufacturers.

I have a mate who's got a doctorate in understanding tyres and he says we only really know 25% of it. That's why so much of tyre performance is measured rather than calculated.

To be honest, I'm trying to make the ride more comfortable, so I thought increasing the profile would make for a softer ride.

Could be wrong though.

The problem is that you'll decrease the revs per mile and increase the ride height unless you also change to a smaller size of rim.

OK, were 15 inch alloys ever fitted to an omega?
Im sure they were available for the Carlton, but can't recall seeing any for the omega facelift.

Maybe there were some for the pre-facelift?

Mine are 17 inch at the moment but after driving an omega that had 16 inch alloys (also with a higher profile) - I must admit it makes the ride even more comfy than with the 17s.

So I am on the look out for 16s or 15s to fit my omega with a high profile (hopefully a bit wider for more traction, but this isnt a  must).

Yup, 4x 15" steelies with 195/65R15 (if memory serves) makes for an extremely comfortable ride .. and more fun handling.

As mention previously, if you are going for a higher profile, than you shouldn't be looking to go wider as well.  This conbination will have the effect of greating increasing the overall rolling circumference of the tyre, which will effect the ride height, as well as your speedo accuracy, and may even cause the front tyres to catch on the arches when on a turning lock.

If however, you simple want the correct size tyres for an Omega, I have both 15" and 16" wheels in stock with good tyres.  :y
