>et40 to avoid problems?

Post by retro_muz » Thu Jan 03, 2019 7:05 am

I can see from searching this question has been asked a lot, but I’m asking it again nonetheless.

My B6 is on coilovers and about -35mm at the min, I’m looking to buy some 8.5x18” wheels but unsure about et fitment, after reading up on here I was convinced I’d need to go >et40 to avoid problems, but the wheel shop have advised 8.5x18 et35 (might just be the set they’ve got in stock).

I want to avoid non-recommended tyre widths too, so min 225, 235 ideally – can anyone offer advice, should I aim for >et40 all things considered?

Cheers.

You don't need 8.5 wide rims , why add weight ?

At 18" the rims come as 8.5 or 9.5 wide.

You can find 18 with 8 without problem.

ET35 will stick out more than ET45, 10mm more to be exact.

Now I'm looking again I'm not even sure they've read my email properly. With my bolt pattern (5x112) I can only see et40/42.

Indeed, so are we saying 8.5 will be a problem?

I'm after advice please chaps, I've seen Passats with these rims on but I don't want problems with rubbing. If 18x8.5 are gonna be an issue I'll maybe look at alternatives.

Put your reg no on rimstyle.com and you’ll see exactly what is suitable for your car, they are really pro.

I can't see how 8.5 could cause any problems. It's definitely not a very wide rim. To know little more how it will fit, get some OEM wheel specifications of internet, for example 17" or even 18" if so big diameter was factory option and your new wheel dimensions enter them in https://www.willtheyfit.com , and you will be able to see how much is difference in all positions. About tyre size I would believe it's 235 what you need. 225 sits nicely on 8inch rim.

Thanks, those websites a massive help.

Rimstyle are recommending et42 and that tallies with another website.

Not nessesarily, the amount of 'stick out' also depends on the width of the wheel.

Weight - adittional unsprung mass , less suspension shock absorber damping , streached tyres , lower profile tyres , pot holes , exposed rim kerb magnets , dynamic losses , acceleration , braking , mpg etc Vs just one positive - looks , if you like that sort of thing .

Hell yeah , personally wouldn't go above 18" and a Audi common tyre size of 245 40 is good with an 8J rim .

Personally I think 245 is too wide for 8j rim, and you will get pear effect, which is last thing you want, especially on big rims. I was running 225 on 8j and there was no sign of stratch at all. 235 would be maximum width I would fit on 8j.

Wheel weight depends more on design and material. That half inch less thickness will give you only few grams less. If looking for lighter wheels, choose smaller diameter rimm. And you will get more exact steering with optimal tire width not maximal. Everyone to their own.

There is minimal difference in weight. I have chosen quite a light wheel. Stretch is minimal. I was running 235/40 18 anyway as that is the factory size for 18” wheels on my Passat. Acceleration and braking, no difference, I let the ACC do the acceleration most of the time now anyway. Mpg is exactly the same

But yes I am poo scared of kerbs now

A std factory fit on my T5 is 255 45 R18 on an 8J, thats what I will fit soon, but it is a heavier vehicle.
