18 inch with 40 profile tyre

[Punk_200sx]

Starting to research tyres now, I'm thinking about jumping up a 40 profile tyre to improve comfort with my upcoming cuscos. I'm thinking Dunlop SP Sport Maxx 225/40/18. Has anyone had experiances with a 40 profile 18 inch wheel in the rolla (i.e. rubbing, comfort, looks, speedo out etc.)

i've got 225/35/18 and haven't had a prob.....

I already have 225/35/18 with no prob its the 40 profile that i am concerned about.

I'm not sure about the scrubbing but the speeding will be out by another +3~4% from your 40 profile.

your current setup already puts you out by around +2%. At the end of the day it doesn't make any diff as our speedos are already out anyway.

Got 18X 7.5 with 225/40/R18

and no rubbing at all even with my king lows in

Ah k thats good to hear. My speedo is spot on now, at 100km/h, i'm doing 100 km/h (used those speedo alerts between melb and geelong) and at 50km/h im doing 50 km/h in the local streets. I was reading through BlAcK JeT picture comments (225/40/18)and he said his speedo is not out all, so prob tyre profile doesnt make too much of a speed difference.

Any more peeps, with coilovers and 40 profile 18's, please let me know if u have any probs.

bit off topic here

i have 215/45/17 Dunlop SportMaxx, 17"x7" +42 offset, TRD Sportivo suspension and scrub badly in extreme cornering (ie on track)

normal street driving is ok even with full load of passengers.

What about the offset... offset plays a big part when we'r talkin bout scrubbing... even if u have the right tyre n wheel size the offset might screw it up for u... FWD usually have around 35+ to 40+ offset it depends on your car, RWD offset is around 15+ to 25+ so just double check...

Well im looking into getting Bridgestone adrenalines RE001 in this size but I am on coilovers. When you say scrub badly do you mean rubber cutting of the tyre:blink: ATM I am on 1.5-2 finger gaps

I run 215/35/R18 on my car and it's not too bad at all...

Bringing this 1 back up again as tyre tread is getting kinda low. Does any1 with 225/40 18's have trouble getting 1st to 2nd lift changes. Please let me know as I am thinking about getting a 40 profile tyre soon
