is any one running goodyear eagle f1 tyres on standard rims I need to know the tyre width measured from side wall to side wall, I know the standard tyre is 225 but the ones I have are 225 across the tread but with side wall bulge they measure 245, I need to know if the f1 tyres are a flat side wall with a square edge where it meets the tread

 

cheers

i am running eagle f1 on the fronts and are 225 but on 18"s gis a shout if i can help

A bit of an odd question - may I ask why you need to know?

 

Whilst the "225" bit refers to the tead width, tyres of a higher profile will generally bulge once the weight of the car is upon them;)

 

Lower profile tyres (like the stock UK spec rears of 245/45/16), having a less deep side wall don't flex so much, so give les "bulge." Also the width of the rim can make a difference; narrower rims would also encourage a little extra bulge, whereas wider rims stretch the tyre, reducing said bulge......

 

I have used Goodyear GSD3 F1 tyres, but not stock size and I don't remember there being any unnecessary sidewall bulging........(see pic)

 

Richard:smw:

whilst swapping the engine gearbox and brakes from a 300zxtt to my 200sx I thought I may as well use the wheels too, thought that would be the easy bit.

 

general opinion on our board was yup straight fit may need 3mm - 5mm spacer, mine don't fit unless I go to a 15mm spacer at which point the tyre sticks out from the arch, the only difference i could think of was the tyres them selves, I have a set of cheap federal tyres, the bulge with weight is not the problem its the overall width of the tyre, I understand low profile tyres are going to have no bulge but I want to keep stock zed rims and I want a tyre with a good speed rating hence the f1.

 

Some one must have an f1 tyre on a stock rim

when you say don't fit, where are they making contact? are you swapping into an s13 or 14? is it stock suspension? are they uk or JDM rims?

Car is an s13, with s14 hubs 5 stud hubs, s14 agx shock, s13 spring, 300zxtt 225 50 16 tyres

 

The tyre is catching the side of the shock body, clearance every wher else is fine, It looks like I need about 9mm to clear the shock but this puts the tyre out of the arch, if the tyre was 225 I would have loads of room but the width of the tyre across the widest part is 245.

 

I don't mind buying tyres for it but I would like to keep the width at 225 I cant afford to buy a selection of tyres to see what will clear, I could drop the tyre height ratio to 40 instead of 50 if that makes the side wall go straight instead of bulging.

 

I cant fit wider arches either as I have an s15 front end to go on the car just to confuse things further:wack:

Stock is 225/50/16

Stock is 225/50/16

 

Yes and i have stock 225 50 16 but different tyre manufacturers have different designs some with bulging side walls and some with flat, a bulging side wall like the ones I have adds 10mm or more to each side of the tyre which is causing the clearance problem thats catching my shock.

Mine has F1's all round 225/50/16

If you want a lower profile in F1's you will need to go down to a 215/40/16

 

There is budget tyres available in 225/45/16 but no f1's

This may sound daft but seeing as you have the tyre I'm after :D, can you put a straight edge across the wheel both sides and measure the tyre's maximum width Please, a picture of it would be good too, I,m not after a budget tyre I just don't want to buy tyres that don't fit the front

So you just need the girth of the tyre measuring?

 

Ill get my tape.

I make it to be 236, cant post a pic up though.

ive also got some bald F1's on some stock rims at my parents house, dunno how local you are but your welcome to borrow one for a test fit.

236 may just work with a 5mm spacer, I,m up in Newcastle its a bit far to pop round, thanks for the offer though, do they have a rim protection rib on the outside edge ?

2 secs back to the garage again

They dont really have a rim protector as such but cos of the shape of the rim and tyre they do give the wheel enough protection.

 

I just re measured it and id say ive been qite generous by saying 236 may be a couple of mm less, but better that way than the other, id still try a test fit before pouring £400 into new tyres though.

Thanks, the rear's will be fine its just the front that's the problem, infarct my next job is to try and find a pair of the wider 8.5 rims of the later zeds :D
