    ET35 alloys on a lowered MK4?

    Okies, my in-need-of-a-refurb-badly 17" Kahn RSR's turned up today - however they have an ET35 offset and not the ET49 offset the eBay seller listed them as.

    Given my MK4 hatch is lowered by 40mm (sits a bit lower at the back due to LPG tank and sub box), and I was hoping to put some 215/45/17 tyres on, am I asking for trouble or will these fit OK?

    How wide are the wheels?

    I had 18" with 215/35/18 on my astra before, 7,5j wide, also ET35...no problems at all. Only in the front it rubs in the plastic a bit, but that was because I was driving much lower than 40mm.

    Why 215/45/17 if I may ask... it should be 215/40/17?

    The wheels are 7" wide. They have a mix of tyres on now but all are actually 205's which look a perfect width to me. Would that reduce the chances of rubbing?

    I personally prefer the 17" wheels when they have a 45 profile tyre on, the 40's just look a bit skinny to me - one wheel has a 45-profile on so I might try the fit on this to see how it copes, at least then I can keep or change the tyre size if required - I'm not going to get these wheels for £40 again

    Should be ok then using 45's on a 40mm drop?

    17*7j ET 35? It should be fine with 215/45/17's. It may rub a bit in the front in the plastic when you hit a bump with highspeed, but it's no biggie...just some plastic.

    Excellent, though it's the back I'm more concerned of due to it sitting very low.

    Any reason why I can't stick with the current 205 width of tyre instead of a 215? It seems a perfect width for the wheel to me?

    205/45 or 205/40? Both are fine actually...as in fitting it. The only 'little' thing is, a wrong tyresize will affect the shown speed.

    Width won't affect speedo readings - the 205/45/17 profile is a little larger than the current 205/50/16 tyre and the 205/40/17 is a little smaller than the current, so it makes no odds really.

    My SatNav reads ~3mph below the speedo figure anyhow, so a 45 profile tyre will probably bring things into line if the AOC tyre size calculator is anything to go by!

    That aside, am I OK to use a 205 width tyre on a 7" rated alloy? As I say, it looks 'correct' to my eye?

    Right, cross-posting between two of my own threads now...

    Geoff gave me (OK, he did most of the work!) a bit of his time tonight and we tested the two Kahn's with the 205/45/17 tyres on to the front and back of my car.

    The rear is pretty much perfect, there might be a teeny bit of rubbing if you drop the suspension fully over a bump but even with some 215/45/17 tyres on they'd be fine. Fronts were a little tighter, you'd get away with a 215 width for the roads I use for work I'm going to stick with 205/45/17's all round.

    Interesting to compare the 40 and 45 profile 17's against my current wheels (205/50/16) - the 40 profile was much smaller than the current setup, the 45 was almost identical, perhaps marginally bigger. No way on Earth I'd put 40 profiles on, the tyres look sooo thin and just do not work on the car and make the wheels look smaller than the current wheels!

    Do you have a pic of the 205 tyres mate? Is there much difference?

    Agree that 40's look to small and skiny! 45's are perfect if you ask me! They don't look too to big.
