    Hi all

    Yes another tyre / wheel thread, I have searched and read through most on hear but still have a question regarding tyre size.

    I'm looking at some reps 19", ET45 8.5j which I believe I can fit with my standard sline suspension with 235/35/19's without rubbing and maybe with 245/35/19's with some spacers. "Correct me if I'm wrong"?

    I would prefer to run without spacers.

    My main issue is with the 8.5j and it causing a stretched look with the 235s can anyone post some pics of there 235/35/19's on an 8.5 wheel as I'm not a fan of that look?

    Many Thanks Adam

    Not the greatest of pics but I have 235/35/19 8.5j on mine with H&R springs, 15mm spacers on the front and 10mm on the rear and no scrubbing. Had 225s before but I hate the look of stretch tyres so 235 is the max I could prob run without scrubbing, with standard suspension I would think you could use a 245.

    Can I ask what drop H&R springs you're running? Did you bother with B5 caps up front to level it? Been saving to pull the trigger on some 35mm drop H&R's to go with some B5 caps up front. It's a daily driver so not slamming it to the deck but want a tighter look.
    Cheers, Leigh.

    235's best for 8.5, 245 only really works for 9.5 (had both on mine)

    Here's my b6 with 8.5 all round with 235/35/19

    2wd car so 35mm H&R springs, pictures above are without b5 cups and just the springs. I did have B5 cups but removed after one day, couldn't clear centralised speed bumps and scuffed my drive so took them right off again and car settled fairly level without them.

    I'm having the same conundrum of what springs to get for my daily driver. Don't want to be having to avoid speed bumps all the time and live in the fear of clipping the cupra splitter on a kerb.

    Any other recommendations other than the H&R 35mm's?

    Thanks for the feedback. It's speed bump city around here so the advice on B5 cups is well worth knowing :yes:. How do you find the ride? General consensus is it's better than stock S line?

    DieselJake, can I ask why 245 only really works for 9.5 please as I'm interested in 245's on an 8.5J for the load factor.

    What problem occurs with 245's on the 8.5J is it technical or appearance. Many thanks.

    I run 245's on an 8 1/2 inch wide rim and they are flush with the rim so they fit fine.

    245 on a 9.5 wouldn't mean you had to stretch the tyre as say a 215 on a 9.5. Tyre stretch looks good but makes the rim prone to kerbing as the rim protrudes the tyre wall. Also can make fitting difficult.

    There would be no issue with 245 on a 8.5 other than potential speedometer accuracy problems.

    Technically they should work but 245 will be on the wide side for an 8.5J alloy.

    Not true, a 245 and indeed 255 are perfectly normal OEM fitment across many brands of car. 235 is beginning of stretch obviously minimal on an 8.5j wheel, the 85% rule confirms this.

    Bit of an urban myth this one, stretching or the indeed the opposite has little or no bearing on speedo accuracy. The steel bands in the make up of the tyre that run round the circumference cannot be stretched or shortened so stretching etc cannot affect the actual rolling circumference.

    ^^^ As dpaz said, could be around 5% depending on width too.

    "Technically they should work", as images show 235 is (if at all) barely stretched on 8.5J. If we must speak OEM fitment Audi puts 255's on 8.5J 19's which cost more, are worse on economy, won't look right and will rub if the car is lowered especially with spacers.

    OP resolved this issue anyway.

    A whole 1%!! If that affected speedo readings that much we'd be changing tyres every 6mths due to the wear alone;-)

    Sorry, my bad. When you said "Technically should work" that implies to me that in principle it should work but is not the norm when in fact it is perfectly normal to run 245, 255s.

    Cheers for all the replys guys, don't suppose any of you have towed anything with the 19s on?

    Just noticed that they have started doing the reps I'm after in an 18", I won't be messing with the suspension so I now have no idea what to do?
