hello,
i bought a set of revolution 8x17 wheels for my sierra and i want your suggestion for the dimension of the tyre is better to fit.

waiting your posts!

thanks

 

215/40 will be best

 

225/40x17 the wider the better, at least on the rear with 215/40x17 on the front.
tabetha

 

i have 225 35 17 on the back of mine with no probs

 

4x4 or 2wd?

 

I agree with Tab, however, if you have the same width wheels all-round and own a 2WD I'd put on the same tyre(the 215/40) all-round so you can swap wheels from rear to front (O/S/R tyre to O/S/F; N/S/R to N/S/F and vice versa) . Otherwise you'll be buying new rear tyres every other week.

 

Why would you?

 

If its a 2wd i would go 235/40/17 on the rear and 215/40/17 on the front. I have ran this set up for over 18months and the wider tyre on the back really does make a massive difference, funny old thing bigger contact patch = More grip.

If its a 4x4 then 215/40/17 all round or it will fook the centre VC up.

 

thank you very much for your posts! my saph is a 4wd so from your answers i'll go for 215/40/17!

thanks again!

pics very soon!

 

Because they're worn

 

Wide tyres wont wheel spin like a chav everywhere so will last longer as there not getting wasted. Who cares about swaping tyres front to back? Give me extra grip any day of the week. It will cost the same in the long run anyway swapping them front to back.

 

So now even wheelspin is chavvy? Please....
Anyway, if you swap rears to front, let's every 2 weeks (also to account for the negative camber lowered Sierras suffer from) you will do longer with your tyres. Agreed, eventually you'll need 4 new tyres rather than 2 rear tyres more often. But that's just my opinion and that's what a forum is about, right? Sharing opinions and facts where applicable.

 

Don't launch/wheelspin etc, and also got a 6° rear beam, so don't suffer from wear on the inner edges, and they wear evenly!

 

i run 215-40's on mine, works fine, no scrubbing and grips well enough

 

I dont even have a modded beam just some shims and i dont suffer from un even wear. Funny how the 2 people on here who are saying why swap front and backs are the ones who have sorted there alignment issues.

Whats the point in spending ££££££ getting more power if your car doesnt have any grip do to skinny tyres or not botheriing to sort you alignment out?

 

ta 225 na valeis,alla na tsekareis poio apo ta 2 diladi to 45 h to 40 einai poio konta sthn mama diametro

 

Exactly! Obviously a bit more mature than to do donuts in Tesco carpark too mate
