Can anyone help/advise if the low profile tyres on my 3.2 52 can be replaced with a not so low profile size?  thanks

[JamesV6CDX]

Stick with standard - there is no good reason not to... 

[Jimbob]

also - what have you got?

standard is 235 45 17

someone may have put slimmer on at some point.

In purely physical terms...

If you look in the top of the front wheel arch you'll see the spring cup on the shock sits above the tyre. There is very little room until the tyre would rub/jam.

Question is why ask?

Not unless you use smaller rims. If you replaced the 235/45 17 with a tyre of eg 235/65 17 (is there such a size?  ) then the over all diameter will be bigger than it should be, which will result in the speedo being way out. You could fit 16" rims with 225/55 tyres http://images.omegaowners.com/documents/UserGuides/OmegaOct2002.pdf page 227

You're better off though if you fit the correct tyre & rim

As chrisgixer said, increase the overall diameter of tyre, it will foul the shock. So the only way to increase profile is to use smaller rims, so the outside diameter remains the same.

thanks all you guys for help in that question - the reason for wondering was the fact I have mudflaps that bottom out quite regularly on the road when a little more than a gentle dip occurs or again at less sized dips but at a greater speed - front shocks seem ok (70k from build) and i don't have any float or detectable bounce as weak shocks might show - but can't be sure, there's a lot of weight with the 3.2 up front?

is it Elite suspension? They are not know for being firm!

[Ant - Petrol Blue Thirty Two]

think so as i know the rear springs are a softer elite spec coupled with the adjustable rear shocks - so presume front legs are factory spec and are original - the front end as you know slings quite low anyway and the mudflaps are shortish but still scrape regularly 

[Darth Loo-knee]

I think the life of a shock is about 50-60,000 miles.

[Shimmy]

I took my mudflaps off, they were cracked, damaged and shabby looking anyway.

Not had any bottoming out issues though.  My Elite has some lowering springs a former owner must have fitted/specced, they're red so I guess maybe irmscher?

[MaxV6]

my experience is that scraping flaps is a dead give away for knackered shocks....

totally fubarred shocks on an MV6 for example, sometimes still seem able to pass an MOT ....   as long as there's no obvious leaks.....  and it is possible to do that if they're so knackered there's nothing left to leak.....    i know,  that's the state my last lot were in....

[feeutfo]

Is self leveling working? Any broken springs? Elite is a bit wibbly wobbly. Comfy though.

there is a 215 tyre which gives a higher profile and still the same hub height, but I suspect that's not what you were really asking.

if you just want to riase the car off the ground a bit, then you mustn't do this with tyres. The rolling radius of hub-height is best thought of as the "god" dimension and mustn't be altered.
