I've decided that next winter I shall be fitting winter tyres to the car (we live down a country lane that is still like an ice rink). Even in a normal winter I spend alot of time driving of muddy back roads so they should benefit with stopping on those too.

Consequently I want to pick up a spare set of wheels sometime, will anything 33 steel or alloy fit?

Cheers

Jeremy

What about 145/6 spare wheels, 4 from a scrappy with winter tyres fitted?
Very cheap as there very thin and should cut through the ice and snow?

So 145 & 146 are the same bolt pattern & offset too yes?

145 and 146 will have the same bolt pattern (PCD 98.) but not sure about the offset. You'll find most Fiat four studs will have a PCD of 98 but I guess the offset would vary and you'd have to check fitment before buying.

[JeremyC]

Is it safe to assume all 33 wheels have the same offset?

145 146 155 all 4x98mm

I'll post offsets later if it helps

I remember spacers required to clear rear trailing arms. If I remember correctly 145/6 ET49 or something to Et 40 of 33. Also cntr bore bigger by 0.5 mm.

Just been out into my garden to read-off these:

Alfa 145 Cloverleaf Speedline : ET 49.5

Alfa 33 QV Speedline : ET 39


145/146 boxer-engined cars may well be different offsets to the Twinks

Hi

There is a page about it up there ^.

http://www.alfa-pages.co.uk/offset.php

Basically the offsets on the 33 are the same. The 145/6, etc is different, and also have a very slightly smaller centre locating hole.

Heard a few people mention using a space saver. However not sure that the tyre bead is the same, and while they are narrow if you use the original tyres they also have a very low speed rating, very short life expectancy and very little tread.

Set of old narrow rims should do the job OK though, although you might need to change the wheel bolts as well.

All the best

You should chk. The space savers are narrow and there's a possibility it might clear.

quick question here as you're on the subject of wheels.

I need to swap the front and rear wheels due to wear. First time with my alfa.

I've never seen balance weighs on these 33 wheels. Do they attach them to the inside of the wheels or do they not need to be tested/balanced at a workshop?

thanks

All 33 wheels need balancing; the tyre is responsible for most of the imbalance. Weights are fitted to the innner or outer side of the wheel as indicated on the machine when the wheel is balanced, although I have seen balance weights glued to middle of the the inside bore of the wheel.

You should make sure you use the correct bolts for the wheels you fit. They are longer for alloy than for steel wheels.

Non-standard wheels may have even longer bolts, and the wrong bolts could have been installed before you got the car, e.g. if a previous owner had fitted wheels with spacers, then used those longer bolts when replacing the original wheels.

To check, make sure the bolts go at least one thread through the flange or brake drum with the wheel fitted, but don't protrude enough to foul anything.

If long bolts for alloy wheels are fitted to steel wheels, the ends of the bolts on the rear wheels can foul the brake cylinders or shoes.

Thxs RFlower.

I will change the front for rear tyres myself, and drive down the street to have them balanced at my local garage.
