Seems to work fine - I have tried 225/45/17 and 235/45/17 - slightly larger diameter - both traction and oversteer / understeer correction work fine. When you say suspension realigned what do you mean - wheel alignment?

Not wheel alignment... but suspension geometry. I know that each suspension setup is tailored to a particular width of the tyre. The suspension can cope with increasing the rolling diameter, but when you increase the width, the camber which is stock at -1.0 I think, will exert added force on the edge of the wider tyres.

But I think 215 should be ok as Whiteline's site says it's usually when extremely wide tyres are used the handling becomes worse because of inappropriate camber.

Whenever I have changed tyres (ie to 225/45 and 235/45) I always get a laser alignment. Going wider has not pushed camber, toe, etc outside the OEM spec range. It was well within the ranges.

The only time I have seen a change outside OEM range is rear camber when I lowered the car with the Cl9 sports suspension. That was expected - still haven't decided whether to get a camber kit. The rear tyres seem to be holding up fine despite -2 ish camber.

I realise that the dealer was looking after my best interest's & I appreciate that. I have been around cars for many, many years & I know what is legal & what is not as far as tyres go. Yes the edges were worn, probably due to under inflation I think & a very hard run up Mt Tamborine one evening, but the tyres were still very servicable. 50k was not a bad run for the tyres though compared to what some are saying they are obtaining.

The camber stays the same with wider tyres, but wear on the edges might be higher. BUt since your 235s did not have problems as long as it was aligned, then I'll give wider tyres a go in the future. How long did your 225s last?

I didn't keep the 225s very long - around 27,000k. They were still roadworthy Falken 512s (I could have stretched the life to 32-35k if I wanted) but I wanted to get rid of them. They were good tyres in the beginning (up till 20k) but the performance started to dropped off in the wet in a major way. Even very gentle take off in the wet would trigger traction control. The final straw was a trip up north WA - I was doing 100kph in heavy rain in 6th gear. I then downshifted to 4th to overtake. Once in 4th gear I applied the throttle to overtake. The VSA light started flashing as the wheels were obviously spinning.

When you can trigger traction control in 4th you know it is time to change tyres (no matter how much tread appears to be left).

OMG! That's bad. That's one tyre off my to try list.

I have just put the new set on last week end. I have kept 2 of the origional wheels & tyres as spares & had 2 stripped down to the rims. I would say that there is at least 10k more left in the ones that i kept mounted. I got fed up with the dealer ringing me at service time & telling me that I needed new tyres because they were a little rounded on the edges.

Hi Eurotoy,

Can you mount the OEM rims of the Accord Euro, say to a 92 Civic Si or any of the newer Civics or even the Jazz. What would you do with 4 spare rims?

The accord is 5 stud, so no.

Some tyres mentioned on here were tested in MOTOR Dec issue 2005!

Newer Goodyear Eagle F1 - btw agreed old one was crap. Hard high grip initially but loses wet grip majorly only after short time. Didn't want to track straight either was sliding all over the place, even with right alignment/balance. Hope the new one is heaps better as a good as MOTOR saids.

Toyo Prozes T1-R - never tried.

Dunlop Sport Maxx - this Dunlop is Made in Germany! Not Aust or Japan, wow!

Bridgestone S-03s - awesome in the dry but not so flashy in the wet. Lateral grip wasn't there. Need a lot of time to warm up as I have used these before. Better than those Bridgies Potenza G-III these had very little sidewall stiffness for a performance tyre. Grip wasn't that good either! Don't think I will be buying Bridgestones again to be honest!

My next tyre to use would be - KUMHO ECSTA Sport. Never used them, but did alright in MOTOR and relatively cheaper! Don't think they will last that long though from others' opinions of KUMHO tyres. Would like to try it once just to see anyway!
