MNR FREQUENCY ASKED QUESTIONS
quote:
For road use ET35 (Ford) is recommended, but for track/race use we have found ET18 (Peugot) to work the best.
Went to order my wheels today and the guy at halfords and my local tyre place didnt have a clue, i asked for a ET 35 ford 205/50/15 for the back and
195/50/15 for the front, (with toyo t1-s tyres on 7 inch wide alloys ) i take it thats what i need for
but they asked what hubs i had and couldnt under stand how they would fit comfortably ( ive ford XR4 rears and Cortina raceleda replacement
fronts!)
can any one help and tell me whats the max width i can fit on back and front and whats the best offset! for fast road use and occasional track on a
rt-plus car!
and i want the biggest width i can fit on the back!

7 inch with 205's is about as wide as you can go...
Hubs are ford so just tell them ford 4 bolt hubs, they are all the same.. ET 35-38

not sure if I'm reading your post right, but the ET figure refers to the wheel itself, not the tyre. It specifies how far offset in mm the face
that mates with the hub is from the centreline of the wheel.
The "Ford" part refers to the stud spacing (or PCD).
As it happens, Peugeot use the same PCD as Ford, but generally with bolts instead of studs. However their wheels are commonly ET18 (probably due to
being FWD) as opposed to Ford's ET35 for RWD cars.
The 205/50/15 figures then obviously determine the width, profile and size of the tyre, which needs to be suitable for the wheel size and car (wheel
arch clearance etc).
As I say, may be reading your post wrong though.

yea i know all that, and ford are et35 PCD 108 wheels and Peugeot are et18 108's! thats not what i was asking, i was jst trying to ask what is
the best and the biggest wheel and tyre i can get on (15 inches in size of course)
in MNR FAQ's it says ET 18 or 35 can be used on the vortx, but if im going 205 50 15 i want to know which one will leave me the best amount of
room on my rear arches, and if i should just get 195 50 15's on the front

yea thats what i asked for i told him ford fitment but when he asked about width clearance i had to tell him what car and they got all confused!
Ive just when to alloy motorsport just before i got you replys guys and ive decided on 195 50 15 et35 fronts and 205 50 15 rears on 7 inch wheels!
So yea thats going to work out about right to what you have said!
oh and T1-s tyres aint being made no more just t1-r (the new ones) so going to cost around £600 for superlegeras/or superturismos
ps they are selling of the T1-s for £40 a tyre in 195 50 15's if anybody wants any

On mine, OZ Superleggeras, ET38, Ford fitment, 205/50x15 toyo 888's...
Bought from MADS on ebay, cheapest I could find...
I now have some 17x8 Superleggeras on my Scoobie Forester Turbo as well

Just a thought - why the 15" rims? A 15" wheel/tyre combination will be heavier than 13" or 14", the wheels and tyres will
generally be pricier and the stiff, low-profile tyres will reduce ride quality, especially on such a light car.
Cheers,
Eddy

Cheers,
I can see where you are coming from but, the wiehg issue depends on rim quality i could get a standard 13 that is much heavier than a 5kg comp wheel
and A 15 will look a lot better, fill those arches and you will never notice the difference of the ride quality between the 2, the side walls will
still be a few inches thick!
And if you notice in my archive, my audi had a set of 20's (lowered 60), my clio a set if 18's (lowered 100mm) and my latest brabus has 17
205 40's and i dont notice a poor ride quality, they feel fine to me it may be i like to feel the road or i might just be/have a soft arse

I run 195/50/15s on mine with ET35 rims on sierra hubs all round. Handling is spot on with 18 PSI at the back and 17 at the front.
Would ET18 peugeot rims cause the wheels to stick out further? These would cause my rears to foul on the arches. On the fronts it wouldn't
matter as you stick the front arches on to suit. The wider track should improve grip in theory.
As for 13" rims, 205/60/13s have exactly the same rolling circumference as 195/50/15s according to my michelin data sheet. Sizes do vary from
manufacturer to manufacturer though. Standard 13" cast rims weigh the same as 15" OZ superleggeras but are about 15kg a set lighter than
standard cast 15s. If I'd known...
