Hi all,
What's the max width wheel anyone has/has seen on a coupe/hpe, and with what size tyre?
Thanks,
Andrew.

7x15 with 195/50x15 (seen this)or probably 195/55x15 (nearer rolling radius but not seen it done) are realistic maximums but I'm sure folks have done bigger, however don't forget that going too big and too low a profile will spoil the handling and ride and cause premature suspension and bearing wear

You might just sneak a 205 on a 16" rim without modifications but there are a couple of points;
The PCD of 98mm is unusual - many wheels don't fit without wobble bolts (which have always sounded like a death trap to me). For obvious reasons Fiat / Alfa / Lancia wheels are popular. 16V Integrale ones are 15x7 and look OK on post F/L cars but not (IMHO) on the earlier ones
If you haven't got power steering then you'll find even 185 gives seriously heavy steering - even on the move.

When I first bought my current Coupe it had 205's on it........... re the Steering & handling on a road going car: Horrible, HORRIBLE, HORRIBLE !! IMO The very first thing I did was get those wheels off, I put 185's on after that and the steering was still too heavy.
I would advise to think carefully about this, form over function may prove a bad route to take if you have no power steering.

check your front strut top mount needle bearings it should only be heavy when not moving |

got to be careful using other fiat/lancia/alfa wheels over offsets as the Beta uses a different layout to later cars which were more Fiat orientated they never did wheels quite as deeply dished as the beta on later cars, also spiders appear to have more restricted space in the rear arches than coupe/hpe |

Just to clarify: These will fit straight on without spacers? Andrew. |

IIRC the Beta offset is 34 and the Integrale offset is 30 so with and 4mm difference the likelyhood is very high.

useful website calculator http://www.1010tires.com/WheelOffsetCalculator.aspI reckon they'll be a close fit but the fact that they are a bit bigger diameter helps as it helps the inner rim to clear some of the obstacles that a wider 14 inch would probably hit |

But with the wheel being around 38mm wider that offset means it's a lot closer on the inside. Too close, methinks... but I suppose there's only one way to find out... so: Who's got a 16v Integrale in Cumbria?  Andrew. |

my after market wheels are 27mm offset haven't tried them yet in anger as the car has been off the road since 02 but a dummy run a while back suggested they fitted ok clearance was tight though

With... probably... the same backspace though? The potential problem of them being too far in would remain the same. my after market wheels are 27mm offset haven't tried them yet in anger as the car has been off the road since 82 but a dummy run a while back suggested they fitted ok clearance was tight though
Ok, but what width are they? Andrew. |

I ran 7x15 with 195 x 50 yokohama on my Beta Spider with power steering and 180bhp engine and would describe it as perfectly weighted even with the camber at the front set to 1.5 degree negative. Bigger tyres on the rear are an issue on Beta Spiders without the arches being modified. I have seen 205 used and will be doing so on my VX Powered Beta Spider. One note of caution, if any part of your suspension is bent bigger wheels and Tyres will highlight the issue. I put 6 x 15 wheels and 195 x 15 x 50 on Terry Woods car and he has enjoyed driving it.

Eric, this is encouraging information! Do you know what wheels they were and what offset/backspace?
Thanks!
Andrew.

Wow
It is like seeing an old friend. I got them with a car so I never got to the bottom of the supplier, but they are super light and looked great on the car. From memory 7x 15 ET27 (offset). I look forward to meeting some proper Beta owners again at the NEC show this year.
