Urgent trackday tyre advice needed

[Gary H]

Hi - I need to get some tyres for a weekend at the Nurburgring and Spa this weekend and have just been told that my preferred tyres are out of stock in the standard sizes.

I'm running a pair of 987 17's (6.5's and 8.5's IIRC) and was going for a pair of 205/50's and 255/40'17's.

I've been offered the following:

Option 1:

215/45/17 & 235/45/17

Option 2:

225/45/17 & 245/40/17


My only concerns are: will a 235 be too narrow for the rear - and will a 225 be too wide for the front?

I need to do something today, so any help appreciated.

ive seen people run 245 upfront with 245 rear for a square setup. right now I have 225 on the fronts and 265s on the back

personally from those options go 225 and 245 have fun but if you really have a 6.5 fronts then i wouldnt do 245s up there good luck

Cool - Thanks

I don't think any of the sizes you mentioned are going to be a problem I'm running 275/245 with 10mm spacers

Gary, why not go with a mix and match.... 215 and 245?? You really don't want to go with a 225 on a 6.5" wheel...

[Gary H]

Thanks - Curious - why?

[TriGem2k]

6.5" wheel wouldn't give a 225mm tire enough support. Minimum for a 225 is 7.5"

Kumho recommends 7-8.5" rim for a 225 tire. A 6.5 is not ideal. Will it work? Yes it will.

Great - thanks for the clarification
