Thick Question about Wheel Sizes - Sorry!
I currently have BBS alloy wheels 185/60/R14's on my cab.
My alloys are looking a bit old and bashed and one has a tube in the tyre due to a poor seal.
Can I change to 185/55/R15's? What other adjustments do I need to make? Or is it a simple swop?
Sorry for the thick questions

15s won't fit a 14" wheel
I'm guessing that you want to know what 15" wheels to replace your 14" for?
I'm running 195/50/15 but will be changing to 195/45/15 or even 195/40/15

You missed the funny part Paul!

I figured Sharon would be changing wheels as well as tyres, it did cross my mind though……..anyway its possible. You know tyre stretching? How about tyre shrinking?

Have a look at http://www.rimstyle.com/ it may be cheaper to buy 4 new wheels and tyres .
Cheers ……………..

The key part of your tyres is the last part in your case 14
So any tyre will fit within reason if its 14
If you replace your wheels for 15" then you will need to drop your tyre profile to counter the extra inch
so to keep the same rolling radius as your current 14" wheels you will need a 195/50/15 tyre.
also you will require a wheel with a 4x100 pcd and a centre bore of 57.1mm and a et (off set) of around 38. your current bbs will be at a guess ET 30.
Hope this helps?

Rimstyle.com is bad for my bank balance, but there's some great deals on it.
Thanks for your advice.
last dumb question, can you explain the "offset" to me? Sorry

Effectively the offset is also the distance from the centreline of the wheel to the hub face.
Therefore :
If you put a wheel on the same hub with a bigger offset, the wheel will sit further inside the wheel arch because the wheels bolting face will have to move further in to meet the hub.
Alternatively if it has a smaller offset it will sit further out from the wheel arch.
For sports purposes grip would be improved by increasing the width of the wheel(and tyre) and using a smaller offset to allow for the extra width on the wheel in the wheel arch.
More information on wheels
Vehicle wheels are usually described with a designation of something like '13-5.5J' and this is decoded as follows.
The 13 is the diameter of the wheel in inches from edge to edge, measured inside the flange with sizes ranging from 10 inch on the original mini's to 23 inch on 4x4 vehicles.
The second number is the width of the rim, again measured in inches between the flanges. The original mini used 4.5 wheels and sizes range all the way up to 12 as used on some supercars.
The letter, in this case J refers to the shape of the rim. Rim contours are standardized by the Tire and Rim Association, so that tires will fit.
Another important thing is the wheel offset, which is the distance between the middle line of the centre of the wheel width and the mounting surface of where the wheel bolts to the hub on the vehicle. The offset is described by the term ET, which is from the German word 'Einpresstiefe' translated as 'insertion depth'. Most wheels have a positive offset which means the mounting surface is further outboard than the wheels centre. If you reduce the amount of positive ET on the wheel the the vehicles track is widened and vice versa if the ET number is reduced. Straying too far from the original offset can be detremental as fouling to the suspension and bodywork can occur as well as eccess strain on wheel bolts or studs.

I have decided to purchase the following alloy/tyre package
Do you think they would look good on?:
I like these wheels as they are "clean" looking, but don't want them to look too out of character. However, I do think the current wheels detract anyway!
Your comments are appreciated.
And does anybody know what the "performance tyres" included are like, or is it worth specing up the tyres?
Thanks

Sorry should have asked, these wheels are showing no offset listed. Does that matter?
Yes ring them first . Those original Scala alloys look great on your car .
