After faffing around for ages trying to get some 225/50r15's for the front, in a T1R (which seems to me to be pretty good on grip compared to the opposition) and failing with a few abortive attempts to order them on websites that turned out to have no stock, I finally found a website where you can browse for tyres the "right way around", starting with the rim diameter, then the profile, then the width.

And I have turned up T1R's in a 215/45r15 which should just be wide enough for the 8J OZ split rims.

At £70 a corner, not too bad.

You can get Nankang's which have little grip (according to the reviews) or stupidly expensive ones over 200-300 a pop.

In the middle - if you do only small mileage each year - are Kumho's at around £170 a pop, but phenominal grip.

Yeah the choice of width you can fit primarily depends on your wheel width, see here for how to measure it:

http://www.more-japan.com/blogs/2011/08/24/how-to-...

as a rule of thumb if the tyre is still on there I have found you can measure across the outside in inches and subtract 1.

Then if you have lattice wheels they are probably 7 or 7.5J which limits you to a max of 225.

See here for the lookup table:

Then you have to choose the profile (the middle number), on the rear this is done to suit the speedo, as it determines the rolling radius, the front is less critical.

In my case I don't want too wide tyres on the front, max 225, but I can't get them, so the next best thing is 215's. 45 profile is fine for me 'cos I like the front to sit a little lower anyway.

When I changed the rear from 225/50/15's to 245/45/16's the rolling radius went up slightly and now the speedo is exactly correct, which is a bonus.

I am currently running 205/50/15 's on the front 8J rims and 225/50/15's on the rear 8.5J . looks and drives great .
Although im gonna be in the market for some 16" tires soon wink
If that's 'cos you're getting some of those 16" 9J's then the T1R in 245/45/26 is a good tyre to go on. If they come shod then do please try the wheels first for clearance with a drive if possible.

Yeah the Nankangs I had found were a different compound, the TOURSPORT XR611, I didn't come across the NS-2 when searching. They certainly look the business with the tread pattern like the old S-02's. And the review looks good. Seems like they are only up to a 205/5x/15 though. Would be good for a 350i methinks.

just got my tracking number and my T1R's are coming from germany!

Yeah R888's would have to be on a spare set of rims for the summer - even though it's technically a desert over in East Angular, you do still get the odd rainy day, and the ruts on the M11 hold a linear puddle half an inch deep.

Well my T1R's have been on for a few days - they certainly feel different to the ones they replaced, even after reducing the ggarage's stupidly high 34 psi down to 21.5.

Once I've found the right pressure and they've lost their gloss I'll report back.

A 4x4 place keeps advertising they have stock but have none.

Anyhoo I have been running the 215's on the front for a couple of weeks almost, and the steering seems much lighter than the 225's, which initially doesn't instill great confidence, because the instinctive reaction is that it's slippy.

However, the grip does seem to be there, I've been pushing round roundabouts at almost the same speed so far, and no sign that the front end is understeering, so it's all good so far. Still on about 21psi so I might drop that by a pound and try again.
