I just picked up a set of Q4 16" speedlines and was wondering what size tires would look the most aestetically pleasing and ideal... I was thinking 205/55v16 s would seem right but wasnt positive.. So I thought I would get input from those who may be sporting a set on on your 164s

I found this pic and the aspect ratio seems to look perfect for the wheel...

I've been running 205/55/16 for years. Works well.

Have a look at the picture thread at the top of this forum, there you will find plenty of pictures. My Proteo Rosso Q4 is also in there and I put up some photos recently. Mine has the standard size rims and wheels (both summer & winter tyres), as Alfaheida attached a picture of. Standard wheel size is 205/55-16 and that has worked fine on mine for 120.000 miles.

I haven't tried that, so can't really comment. I guess one important aspect is whether the car is lowered or not...

speedo will be off by 3%, actual speed will be 3% slower than indicated which when added to Alfa's apparently standard 5% will give you lots of leeway in your discussions with the local authorities.

Sidewall will of course be about half an inch shorter (205 x 5%) which will show up in the gap between the tire and the fender lip. This should look fine given the size of that gap with stock tires.

I like this handy tire size calculator the Miata guys have posted:
Tire size calculator

A more complex calculator which includes wheel offsets and so on is also nifty:

We have 205/50/16 GTV 916 series wheels and tires on our 164 and they are close enough to equivalent to the original 195/60/15 factory spec. According to that calculator my speedo is reading 0.6% fast, which gives an extra safety margin as far as cameras are concerned. Here is a pic of the car:

Standard tire size for NA was 195/65 x 15 which has the same rolling diameter as the 205/55 x16. Other sizes which are equivalent are the popular 205/50 x 17 and 225/45x17.

!85/65x15, 195/60 x 15, 205/55x15 and 205/50x16 are all the equivalent tire sizes to each other, but smaller than the NA factory size.

My 164 handbook says 195/60/15 or 205/55/15. The pictures in our books show left hand drive cars, so I assume they are European ones. We were provided with a supplement book which detailed things to do with our rules such as seatbelts and child restraints.

Yes. I think North American cars got the taller sidewalls to "improve" the ride, i.e. make it a bit more squishy. Interestingly, the sister car SAAB 9000 was introduced to North America with the 195/60 x 15 tire and was altered around 1990 to come with 195/65x15 or 205/55x16. I think Europe may have kept the smaller tire size for the SAAB also.

In Canada we got daytime running lights ( a relay that switched all the lights back on when you switched the switch to OFF!) and one child seat tether strap anchor also (that regulation changed to one per rear seat position later).

On the European version of the 164, the 195/50-15 size was used only from 1987-1990. With the 1990 revision (new front subframe, green instead of white button illumination, improved window, seat switches, and other improvements), which coincided with emergence of the QV/S and the North American introduction, came 195/55-15 tires - also in Europe. If I recall correctly, pre-1990 V6 cars also had gear ratios that were different from any of those used after 1990.

Are you sure you mean 50 and 55 and not 55 and 60 profile tires? I don't recall a 195/50 or 195/55 tire size in the late 80's.
