I got my cmax 2nd hand a few months ago. It already had a set of huge (bigger than normal)non-spec alloys on it. The problem is, they`re not suitable for my line of work (i`m a taxi driver)
What i want to find out is.....

1...what is the 'spec' size of tyres/allos on the cmax?

2...where can i get a set of 'spec' size steel rims? (I`m in Lancashire)

3...& what sort of prices am i looking at?

Many thanks for any replies

Hello cletus, and welcome to the site.

First, what variant Cmax do you have? Second, what size are your 'huge alloys'? I think original wheel type and size depends upon year and spec. Mine, for example, is a lowly 54 plate 1.6 petrol LX, and has 15" rims, a Cmax in Zetec trim of the same year has 16" rims, etc. Your 54 2.0 diesel sounds like it should have 16" rims, but we can't be sure until we know what spec your car is. Second, you might well find someone on this site who would either buy or swap your wheels with their own.

Does your Cmax make a good taxi?

I think you'll find that the 16" rims were only for the diesel models
I think at least some of the petrol had only 15"

The 16" steel rims are the same 5 spoke that the mondeo has and I had at least one from abgreaker for only £10. As regards tyre prices there are various posts on the various and numerous options

My Ghia petrol has 16" alloys as standard (not that i'm too keen on them)

According to the brochure, all C-Max's above LX spec have 16" alloys as standard, the LX has 16" wheeltrims. It's only the Style that gets 15" wheeltrims.

Better late than never:
All C-max have the same standard size to kick off.
(Fitted 5x108 with ET35 to ET45)


15" with tyres 195/65
this means rims can be fitted in accordance to this size.
For example the
16"need tyres 205/55,
17" 225/45 (215/45 also allowed)
18" 225/40 etc...

This ensures you that your speedometer stays correct by keeping the same
(approx) tyre perrimiter. In Belgium a diff of max 2% is allowed.

The bigger the size of your wheels, the smaller the hight of the tyre(we call it low profile tyres), therefore the stiffer the car feels. What you win in sporty handling you loose in comfort.

Maybe this post can help out max-owners with the same question,
sorry I'm late with respons but than again, I am new

The concensus is that with less sidewall height that the tyres don't move as much sidewards under load and thus the feel of the steering is better but as has also been observed there isn't the same softness to the ride because of less flex in the sidewalls

more likely the springs / dampers set up than the small difference the tyre profile will make
Gas shocks as opposed to oil can also make a significant difference

where did you get that size for the 17 inch tyre size as i was checking tyre pressue chart in driverside door pillar and it says tyres for 17 inch wheels are 205/50 and no mention of the tyre you mention which is surely a larger tyre,
just curious as ive bought a new set of the ford 17 inch 9 spoke alloys which come with the 205/50
tyres
cheers

I know there is a post somewhere from me in the same context where I found the equivalent rolling radius for all the sizes of tyres.
I'll see if I can find it again as this is the best way to judge equivalent sizes
