how wide is too wide??

[nemesisteg]

anyone out there in an itr or anything similar run 225 semi slicks?? or just any tyre, i guess they would be exactly the same. at a glance of my car currently running 205's the front seems to have a fair bit of room to move but the back is pretty close to the gaurd, saying that they have never been rolled and have like 15mm lip on them?? so plenty of room to be made by gaurd rolling but how much more are the 225's likely to stick out?? just want to know bout any experiences people have had with impossible or difficult fitment etc. i know its alot to do with offset blah blah but my wheels dont seem to have the offset stamped on them anywhere so not much help there

[nva2nd]

I have some 225 o2g semi's at work you still got those spare rims no tyres on them?

Could pop them on and do a dummy fit?

[nemesisteg]

ive got 2 15" rims sitting there doing nada. run 16" rims that are possibly a rwd offset, when i say that tho they dont stick out more than old rims but they have huge amount of clearance of the front brakes unlike most fwd offset rims. the wheels were on a laurel before i bought them. ive gotta sit my car up on blocks for a while anyway and strip the tyres of the rims that are on there now, ive bought a set of 205's but im looking at some 225's aswell

[nemesisteg]

also while we are on this topic, anyone got a hook-up of tyre fitting in h-town?

[BTLF3D]

i run 225/50/15 all round, here is a pic of the clearance on 15x7 +42 wheels.



as you can see the tyre rubs on the gaurds (they have been rolled) and also the bumper, not really a big deal tho... oh and they also rub on the trailing arm a little tiny bit when cornering hard.

[nemesisteg]

think i might just get a couple and fit them, im pretty sure they would fit on the front fine. at the end of the day would it be ok to run 225's on the front and 205's on the rear??

[BTLF3D]

yea get some fitted and see how much clearance, the front is fine, only some rubbing under full lock which you wont be doing on the track anyway.
yes it will be fine to run 225 front and 205 rear but watch out for oversteer i have done it before without the type r rear swaybar, i dont think i would do it now with the type r rear swaybar tho...

A thing to note is rim width, there is no point having a 225 ballooned up on a 6.5-7" wide rim. They need a 7.5" minimum, personally id be inclined to run an 8" wide rim.

The handling caractoristics of a car will completely change with rim width.
Race tyres have very rigid sidewalls compared to regular road tyres and to make the most of these, you dont want the sidewalls looking like this \ /.

I think your understeer problem could partly be to do with this Hayden.

I have seen over 1s a lap dropped off times just changing rim width from 6.5-7.5"!

Agree totally, not to mention it just looks funny.

Drifters do the oppisite

yes but it is hard to find 8" rims in NZ... i have tried.
Also i dont really have understeer now with the type r swaybar etc.
i am trying to find some 15x8" wheels but they are pretty hard to find.

[AJbrwn]

i run 225s on the front and 205 kumhos on the rear of my turboed ek race car on a 7" rim and didnt have a problem. wouldnt go any narrower than that tho.

[Dionysus]

Wouldn't 225's tramline a bit for everyday driving?

[nemesisteg]

my car hasnt been drivin since maybe december?? lol dont know that daily driving is high on my concern list LOL
cheers for the input people, rang the guy about the tyres and he is just round the corner from me so im going to catch up with him over the weekend and get a couple to test fit on the car

soon to have two sets!! :-D

I can get you some 15x8 4x100 @ 25p hayden........brand new

and I can get 4x114.3 @ 0 offset

[beeker]

We run 16" 225/45 on the DC2 ITR tarmac rally car. We run 42>45 offset, else it can rub. Rolled fenders are a must, and only a few rim designs will also clear the Wilwood 4 pots on the front. Our current preferred rim is a Buddyclub P1, but its only a 7". Would love to find an affordable 7.5" or 8.0" 16" that clears the brakes. 15" wont clear the brakes,and 17" is too high a rolling radius.

We run Dunlop tyres, as its predominently Targa Tarmac use (mandatory for targa). Note: Suffered from snap oversteer until recently when we started dialing in more rear camber - so far so good.

pm me a price, allthough i am probly getting a decent track/street wheel/tyre combo volk...

[PizzaBoy]

I've been running 225/45/16 Dunlop 02G on my DC2 recently with 16x7 +42 offset wheels (actually +45 with a 3mm spacer, lol)

They just fit with the rear guards rolled, and the fronts have no problems at all.

They do balloon a bit on the 7" wide wheels, but I'll be fixing that soon with some 16x8 rims

what 16" 8" 42>45 offset wheels are you looking at ?

[XPLOIT]

While we are on this topic, does anyone know how wide I can go on factory 16" Euro R wheels?

Im trying to find some semi's cheapest avail is 225 wide....

Cheers,

Cheers,

it all depends on how wide the wheels are... if they are 7" you can probly fit a 235/245 on but they will baloon when you go to wide on a small rim...
in the pic up there i posted that is a 225 on a 7" rim.

[XPLOIT]

Yea I think they are 7"... Would I have trouble with body/componant rub though?

[BTLF3D]

you will have to have a look, i dont know how much clearance there is on accords...

FD RX7 (+50 offset) rims with whatever spacer is needed to fit them without any rubbing
If I had some more coin I'd be looking at a set of 16x8 +40 rota slipstreams


You wont get any wider than a 225 on a 16x7 rim, unless you go for a massive sidewall. Remember a 225/50/15 has a taller sidewall than a 225/45/16 so will be able to fit on narrower rims

Are RX7 they not a 5x stud?

Who sells Rota in NZ ? Whats the Quality like - thought they were low quality?
