Tyre size

[Steviec]

Im looking at getting a set of aftermarket 17" alloys but what tyre size would I need?

[jonbuoy]

Depending on the off set of the wheel?
Usual size to go for is 205/40R17

The off set on my wheel's is'nt to the edge of the arche so i wacked on 215's on the back and it's had 225's on without rubbing on a 40/40 drop

[Steviec]

Thanks for that, dont suppose anyone knows the alloy fitment do they?
The TSW website states that none of their wheels will fit the E30, I find that a bit odd.

[touringshed]

any alloy with 4 by 100 stud pattern and an off set between 25 and 35 will fit u can push to a 38 off set

[Steviec]

Their site lies then! lol
They do the wheels I want in 7Jx17 in Size
4x100 PCD Ԛ—a ET35 Offset

Just gotta work out if I can afford them this month or if I have to wait....

with a offset of 35 and only 7 inch wide the rim may sit too far into the arch, and would not look very good, IMO.

[Steviec]

Bugger, maybe I cant have the wheels I want then! Would be alot easier if I understood the fitments.

[StuBeeDoo]

IMO, 7" rims need an offset of 20-25mm to look right.
As Nav said, more than that and they sit too far into the arch.

Is it not something you can get round by using a spacer?

[bavarian3]

You can get around it via a spacer, but a lot of people don't like using spacers for various reasons.. though if you aren't tracking the car, then many don't mind using spacers and longer bolts/studs

Just checked the site again and it says:
Sizes
20x10
20x8.5
20x7.5
19x9.5
19x8
19x7
18x9
18x8
18x7
17x8
17x7
16x7
15x6.5


Bolt Pattern
4, 5 Lug Finishes
High Gloss Silver
Hyper Black
Chrome

Offset
+20 to +42mm

I assume that means that all sizes are available in a +20 to +42mm offset then?

[nav786]

go for offset of 24 or 25 if you can.

[jonbuoy]

Unfortunately i already bought my wheel's without knowing about offset's, i like the wheel's but the offset is'nt that great.............................

[nav786]

what offset are they, looking at the pics look quite high

[Steviec]

go for offset of 24 or 25 if you can.

Would that still be a 25 offset on a 17" x 8" wheel, or is that too wide? Sorry for all the questions.

I'm not sure mate, i was hoping you could tell me that
