What tyre setup to go for?

Post by Floydian » Sun Oct 08, 2017 12:05 am

Hi,

I think it's time I ditch the oem rft tyres. I am thinking of going for Goodyear Eagle F1 AS3 tyres.

My car current has style 383m rims (fronts 17x7,5 225/45R17 - rears 17x8 245/40/17)

I've noticed wear on the outside edge of the front tyres. I believe there are four possible setups I can go for with the same rims:

A. Factory staggered 225/45R17 fronts and 245/40R17 rears

B. 225/45R17 fronts and 225/45R17 rears

C. 235/40R17 fronts and 235/40R17 rears

D. 235/40R17 fronts and 245/40R17 rears.

What I want to achieve?

1. More controllable oversteer and less prone to snap oversteer.

2. Increase or maintain overall grip.

3. Less understeer.

I am totally confused which setup to go for. Any suggestions and comments welcome.

Thanks

I have two concerns for 235 at fronts.
Is there a risk of increased hydro planning?
Will the wider tyres contact anywhere?

Thanks

Yes, a small increased risk of aquaplaning. I run 245's GY Asym 3's on the front, and they've been absolutely fine. The 245mm MPSS I tried initially were not good in deep standing water.

I guess you have to decide whether you want less understeer and more overall grip, or not? There's always a compromise somewhere. :|

No, 235's shouldn't contact anywhere.

Are your front rims 7.5J or more? I've checked Goodyears website and it seems 235/40R17 nor 235/45/R17 are not available.
