The original wheels / tyres where 195/65/15 91 & the new one are alot wider
I know, but the new setup is still the same size as the old so won't foul the arches. They're only 15mm wider on each side which is nothing.
The 235/45/R17 (above) are larger and wider, but there's still plenty of clearance even with these.
I did not mean tyres rubbing against the arches as there's plenty of room there. I mean the tyres are not rubbing against the inner wing splash guards that are fitted behind the front suspension legs ! when steering is on full lock. I have less then 1cm clearance between the back of rim and the suspension leg.

You can't even get your finger between the rim & Suspension leg !!

Also 18" Rims are far bigger & wider than 17" rims
Yes the new tyres are the same circumference / Rolling Radius, so the speedometer reading remains the same. But they are low profile & 30mm wider than the old 195 65 15 tyres
