Why do you want the wider tyres? Not sure they will fit tbh mate

Ive hear'd of people wanting the stretched look so does this mean it's called the squashed look  :laugh:
I cant see how you could get away with that but why not PM the wheel man for clarification.  :smiley:

245s should fit, but you will probably need to go to a 35 profile.  Is the car lowered or altered in any other way?

One issue which may arise with wider boots and/or lowered suspension is very minor rubbing on the top screw of the front wheel arch liner - if so, just remove the screw, and carefully bend the lip upwards slightly.

How low did you go?

Or do I need to search for your "project page"?  :wink:

The 245/35/18 is 6mm smaller in diameter than a 225/40/18, take into account the squashing effect and they will be about the same.  TBH, ive fitted 245 to a 7.5 rim before and i diddnt like the look..... each to there own though!!

The so called "rim protector" is a load of rubbish IMO.  How is a small strip of rubber 3mm deep going to stop 1200kg of car from hitting a wheel on a kurb????

So how much force do you think is needed to compress 3mm of rubber with a car??  :huh:

Swap the TTS alloys as well :wink: they are 8" wide and will look much better with the 245's. Add to that the missis rolling on Monza's on 225 sections and it should slow her up a bit :wink: :evil:

Huh - actually more like 8 or 9mm difference in diameter!  4.5mm is the radius, and therefore the ride height!  :tongue:

(225/40 ZR18 has an overall dia of 637 to 645mm - depending upon manufacturer [Toyo or Mich], whereas 245/35 ZR18 has an OD of 629mm [Toyo])

take into account the squashing effect and they will be about the same.

WTF are you on about?  If the load rating and the tyre pressures are the same, then the "squashing effect" will be identical, therefore the ride height will 4.5mm lower!

TBH, ive fitted 245 to a 7.5 rim before and i diddnt like the look..... each to there own though!!

Yup, agreed, ETTO.

And just to clarify, a 245 is NOT recommended for a 7.5" rim - with 8.0 to 9.5 being the recommended rim widths.

Ahhhh, but different tyre manufacturers use different methods of "rim protectors".  Pirelli, along with most of the Jap and Korean tyres use the useless rubber "lip" mentioned.  However, Michelin, the latest Continental, and Dunlop - all use the entire height of the sidewall as a rim protector.  This method is noticably more useful than the pathetic 3mm lip still used by inferior tyre manufacturers.

Ref TT: Agreed on the OD, got my sums wrong (no surprise there!)

What i mean by the squashing effect is that the 245 tyre will be pushed in by the 7.5" rim.  The majority of the width will overhang the alloy but i would have thought that there would be a small increase in the height of the tyre (based on no more than what i think would happen, i woulddnt fit this combo to a customers car so i cant say for sure)

I think that joesgti answered you question on this :wink:

OK, no worries.  Afterall, what's a few mm between mates?  :grin:

Ahhhh, I see exactly now.  Yes, agreed, the 245 on a 7½" rim will have a "ballooning" effect, an un-natural kind of bulge in the sidewall.  :wink:  :smiley:  I suppose it's no different to the current trend of "stretching" - which, IMEVHO, must be THE worst mod going - I think that particular trend looks really aweful.  :sad:  :sick:  ETTOT.  :smiley:
