BX GTi Speedlines on eBay

[Philip Chidlow]

Calm down. Nothing wrong with the tyres. Tyres are perfectly fine. As are Athenas...

I said: 'AFAIK' (read: as far as I've been told in the past). So I now know different - it seems.

BUT Why have 6" rims and not use them for a wider tyre: raison d'être and all...

Equivalency table

Rim width , Minimum tyre width, Ideal tyre width, Maximum tyre width,
5,0 Inches, 155 mm, 165 or 175 mm, 185 mm
5,5 Inches, 165 mm, 175 or 185 mm, 195 mm
6,0 Inches, 175 mm, 185 or 195 mm, 205 mm


Minimum tyre size for 6" rims is 175

Where did that info come from Kevan?

Phil, they are 165 because that's what Will had on the car before he bought the Speedlines.

I know these aren't an issue, 3 years fitting rubber rings is my knowledge base. But i've just googled and found this:

I'll also point out they've done 5k approx with no issues.

These are the 6" which require the wider tyres and result in a loss of ride comfort though.

You really wouldn't notice any difference between these and 5.5J GTi alloys. I hardly noticed any difference between these and the standard steelies on the old estate.

When I fitted these to mine with 195 tyres instead of the 165 originally fitted on my steels my car ride comfort was totally ruined, I had to take the 195's off and change them to the minimum 175 size to get a decent ride back. I have no doubt 195 will give better grip (not in snow though) but i prefer ride comfort to grip and my driving style will never hit the limits of adhesion of the 175 tyre.

The /\ links by Kevan are useful and the consensus of whats already been said that 165x70x14 - ARE under size for a 6J rim size which I would agree with too !

So just to add to the /\ links I've found a website (Which I book marked ages ago) where you put in the standard tyre size which vehicle starts off with (the tyres/rims that it left the factory on) then you put in the your new/changed tyre and rim sizes and then you can see what its predicted net affect it has on Speedo readings, ride height gain/loss etc. !

Heres the link for WILL THEY FIT.COM, have go to see the results

Note ! Remember to inform the insurers of any changes from the original tyre/rim sizes to a vehicle, as it may effect the premium or even jeopardize a 100% payout in the event of an claim (Say after an accident) so you have been warned !

Oh dear, did I open up a hornets nest? sorry!!!

I suppose much depends on individual driving style. If you drive gently, there shouldn't be a problem... but if you like corners, there could be.

My current TZD turbo on Speedlines with 185 tyres, is being retired in about 6 weeks time.
Unfortunately the tyres were getting too low, so as I have a set of steel wheels with 165 tyres and legal tread on them, I've fitted them.
What a difference.... it's too easy make the tyres squeal around corners!
