Mk3 lowered springs going from 45 to 40 tyres

[wack]

Picked up my lowered mx5 on Friday, the tyres are on 3mm which is when I usually change them 205/45/17

My problem is I have a set of 600 mile pirelli Nero sat in the garage from a Fiat abarth 205/40/17

It's going to kill me to buy 4 new tyres when these are sat there , will there be any issues if I fit them or is it suck it and see

The ride will be harsher, imo it will look stupid even lowered (the arches need filling out with the tyre not going the opposite way) and you'll also have issues with the speedometer as the standard size is inaccurate and you'll make it even worse going smaller.

That's what I was thinking, I was hoping for a no it'll be fine

I let a local wheel specialist tell me 40-series tyres were right for mine, but they looked wrong, so they came off again. Get tyres of the right size. Personally, I go for Avon ZZ5.

Yep, smaller probably isn't a good idea, seems to be generally accepted it should have had 215/45. Mazda had a modified-ish NC on the stand at Goodwood one year with 215/40 looked odd on them, going bigger still 225/50 on a 16 (for RX7 wheels) is probably better than that.

Only suitable 40 profile tyre on these are 235 or 245.

Given up on that idea , the tyres are legal but odd , I've always preferred the same brand all round, still haven't made my mind up on brand but I'm reading good things about kumho KU39 , I did read the KU31 was good too but black circles don't list it

My tyres are showing the continental contisport5s 205/45/17 88W for £99 each which seems a very good price, the V rated tyres in the same size are £140
