im lowering my mkII squareback by 70mm on a venom springs n dmpers kit (if they ever arrive) and im planning on fitting a set of 6.5"x13" wheels (show you when theyre on)

what tyre size should i go for guys? obv i want this thing low but looking good...

cheers,
lofty

Hmm..

I mean theoretically biggest you can go is 175/50, this is what i would suggest but i don't know if you'll have enough clearence, and u may experience some or major scrubbing without hollowing your arches..

I'm not totally sure but either way i would think 175/50

I would have thought 175/50 was the best choice. Doubt you'll have to do any arch 'persuasion' (Unless theyre ridiculously low offset ?)

Some useful info.....

VW Polo Tuning - Upgrading your wheels and tyres

Polo's made from 1982 to 1994 were usually supplied with Steel or Alloy wheels of dimensions 4.5Jx13" or 5.5Jx13" depending on model and engine power output. Tyre sizes ranged from 135R13 to 175/60HR13.
You cannot just fit any size tyre or wheel to a car, there are limits, one of the most important is the offset. The use of a wheel with the correct offset ensures a proper fit onto the vehicle it is intended for. It can be described that the offset is the distance between (the mounting surface of the wheel), and the centre line of the wheel, this distance is expressed in millimetres. The offset dimension is always stamped on VAG wheels, usually in the form ETnn where nn is the offset dimension in mm.
A MK2 VW Polo is usually supplied with wheels either having an offset of 45 or 38mm, the lower the offset being, the wider the track of the car (i.e. the wheels are stuck out further!).
Polos up to November 1990, usually had 4.5Jx13" Steel wheels with an offset of 45mm, except the Coupe and Classic models which had the 5.5Jx13 wheels (38mm Offset).
The later models, made from November 1990 to September 1994 all had an offset of 38mm regardless of wheel size.
MK4 and MK5 Models have either 4.5Jx13, 5.5Jx13, 6J x 14, 6J x 15 wheels as standard. The offset is generally 45mm (Same as 4 Stud wheels on a MK3 Golf)

Tyre Size Table
Below is a table of standard tyre sizes on the Polo. Most of the wider tyres fitted to the Polo do not use commonly available sizes, so your local tyre dealer may not keep them in stock.
Wheel Size Tyre Size
4.5Jx13" 135/80R13 145/80R13 155/70R13
5.5Jx13" 155/70R13 165/65R13 175/60R13
Polo Enthusiast Mike Smith, has decided to compile a list of suitable upgrade tyre sizes for the MK1 - MK3 Polo, and has listed their effects on the gearing / speedo reading along with some comments.

N.B. Tyre sizes with a difference over standard of more than 2% may affect gearing and or speedo reading by a small percentage, but giving either reduced acceleration times and lower top speed, or reduced acceleration and higher top speed..
