tyre help!

[Puntonick]

Getting New tyres on friday for my Bravo 1.4 SX, Not too keen on what size to get. At the moment the alloys i want to use are 205/55/16 and obviously too big, I was thinking of 205/45/16 tyres, Or would that profile still be too big? Someone help me please!

Maybe 205/40/16?

Could you not put a tape measure on the sidewalls and imagine? I'd imagine that 205/40s'll be a bit too small but you won't know 'till yah see 'em

Alternatively. When you go to get them fitted, ask 'em to grab a few sizes and hold 'em up against your existing wheels?

What size do you have on at the moment?

No I meant what size do you have on the car at the moment, and if it's what you say then did you not know they were too big before you fitted them?

All the info you need...
2% max. difference from original diameter is acceptable.

Getting New tyres on friday ... Someone help me please!

The difference between 205/55R16 & 205/45R16 is 10% of 205mm – i.e. 205(55%-45%) = 20.5mm. Effectively the sidewall is reduced from 112.75mm to 92.25mm – i.e. by 20.5mm.

I believe(?) the within spec tyres are designed to roll somewhere around 883 (±6) revs/ml. A 205/55R16 rolls at 811 revs/ml – & clearly way outside the normal within spec range. Whereas 205/45R16 (867) & 205/40R16 (898) fall within ±2% of 883 revs/ml.

But the choice of 205/40R16 is fairly narrow, the price likely to be much higher (unless you go Chinese) & with a 40% sidewall, you’ll probably end-up funding your dentists new car.
