Tyre Options..

[willgbr]

Just wondering, as ive been on the phone for quite a while trying to order some Toyo r888's or Yoko a048's or equivelant today. They seem to be very hard to get hold of these days!

One bloke said that the Toyo's arent available to the public anymore, you have to be part of a motor club or something to get them now?

Another bloke said that we wouldnt be able to fit Yoko 215's on with Teins as the coil sits quite low and it would'nt fit.

So does anybody know about any of this and can anybody help us with a supplier for the toyo's or the yoko's, or an equivelant which are actually just as good as these for around the same price?

The car is mostly for street use with the odd strip/track day
thanks

sounds like a drop of bollox to get you to buy other makes

yeh rang camskill they said they wont have em in for a month or so :?

 

[pulsarboby]

why not run two sets of wheels as i do.
you can pickup full or cut slicks for track @ around a oner a set once the season gets under way then use something like tr1's for road use!!!
itll be far cheaper that way

sorry it doesnt say what size your after

"The size we are using is 215/45/17" taken from the blog.

Andy Fubar used a similar diameter on his car for a while. He had to raise his coilovers up to make them fit.

As Tein coilovers can be raised to -10mm from standard height you should be okay. Andy can chip in though, I seem to remember him still have some rubbing issues

I have same size tyres on my tein setup, seem to be ok soon eat through the plastic though a bit, not sure on how low there setup but tyre is just under the back arch so low

 

[willgbr]

Oh sorry we are after the widest possible tyres that will fit, somewhere like 215/40/17 or a 45 profile if 40's arent available

I ran 225/50/16 :?

Great for grip, bad for the arches. I did raise my ride height by 10mm to reduce the rubbing, however over harsh bumps it did catch now and again.

215’s should be ok; however as Bob mentions having another set of alloys for track use will be much more advantageous. I’ve got a set of slicks on my Enkei wheels and use Hancooks on my other set for day to day driving/wet track driving.

just out of curiosity what effect would having wider tyres on the back have?
for example 215/45/17 front and 225/45/17 on the rear.. good or bad? :der:

Oh forgot to mention that we are going to be getting the arches rolled and using spacers aswell so this should help with the rubbing and "hitting the teins"..

i run 65mm spacers on rear and 30mm on front and find it definately makes the rear end kick more which is good, i did this to try prevent the understeer (after a lot of experimenting with different sizes).
downside is youll definately have rubbing on rear arches on harsh cornering.

before i had my wide arch kit fitted i made a spacer plate to fit on top of rear topmount to raise the car an extra 10mm but on tracks like brandshatch (where you bottom out at foot of paddock hill) it still used to rub out.
if your not using spacers then i think the effects will be minimal, you maybe better going for a 205mm on the front and 225mm on rear, this should insite a bit of oversteer.









just read post above, forget the last bit i said with the tyre sizes front and rear as with spacers it will be completely different!

I don't think that's a good idea; mainly because you'll have different rolling radii on the front and back which may cause the centre diff to overwork and lock (on the basis that the torque split won't be equal). Whether that makes any real difference in practice I don't know.

Here's my math:
215/45/17 gives you a 17" rim plus 45% of a 215mm wide wheel (96.75mm).
225/45/17 give you 45% of 225mm (101.25) - this is only 4.5mm difference between the two; that's why I'm not sure it actually makes a difference. That's little more than the difference between new tyres and ones on the way out.

I'm happy to be corrected; I certainly don't think 185/45/17 should be matched with 225/45/17

 

[pulsarboby]

it wont cause centre diff to wind up george
it will only do that if you use different size wheels or tyre depths front to rear
ie: 205.40.16 front and say 205.40.17 rear as the wheels will be turning faster on front than rear.
width will make no difference at all

Well right now I can get hold of 2 x 215/45/17 and 2 x 225/45/17 for a decent price. 205 seems to be a bit more difficult to get hold of. The question I have is, do i bite the bullet?

Speak to Phil at Trackside Motorsport on 07974 301464 he might be able to sort you out some 888's failing that why not speak to camskill about the kumho v70's they are just as good as r888's and cheaper!

Thanks for that one, yes he can sort me out, but he said he was unsure about whether to go with the 225's at the back and 215 at the front.. not sure what to do :doh:

Surely on a 4WD application it makes more sense to keep tyre widths the same, what are you using the car for?

Was just thinking about the understeer, will be used for a mixture of things.

 

[fubar andy]

Don't worry about bigger tires on the back to the front, keep to the same size and spend time on your suspension set-up. The combination will help to reduce understeer and you'll find it'll drive better. :thumb:
