Dblock Posted November 6, 2013 Share Posted November 6, 2013 The Z is getting cheaper so people are bound to start cutting corners....you can see it with the for sale ad's as well. How is it cutting corners? Do you not understand there is more choice, less weight, better turn in due to less sidewall etc etc. I'm running Pilot super sports I don't see how that is cutting corners? What tyres do you run? 1 Quote Link to comment Share on other sites More sharing options...

Do you not understand there is more choice, less weight, better turn in due to less sidewall etc etc. I'm running Pilot super sports I don't see how that is cutting corners? What tyres do you run? Because you are not buying the correct tyre size which was designed for the car? So the speedometer, mileage, traction control, torque and gearing settings are all based on the distance that the tyre travels over one complete revolution. A tyre with a different outside diameter will travel a different distance over that one revolution with a different amount of torque. For an extra £30 a corner why not put the correct size tyres on? It doesn't matter if they are bloody F1 tyres....if they are the wrong size its a waste of time.... I agree that it might not make 'that' much difference dropping the profile down by 5 but it is cutting corners Quote Link to comment Share on other sites More sharing options...
Ekona Posted November 7, 2013 Share Posted November 7, 2013 I can see both sides on this one tbh. Dropping a profile will make no difference to the car in terms of maintenance, on the caveat that your particular car is okay with it regarding TCS. Speedo & mileage will be affected, but not by anywhere near as much as I would consider worthy of note. To ignore that completely though would be folly. Many people run 19" and even 20" wheels. These do not run stock tyre sizes and are again fractions out over the rolling radius, but will cause no further issues. I would rather run 40 profile MPSS than 45 profile 040s. One may be the correct OEM tyre choice, but that doesn't make it the best choice. Tyre choice should be made on many parameters, but sticking rigidly with the OEM size is not one I would consider to be paramount*. *Not forgetting the TCS caveat, of course.

Ekona Posted November 7, 2013 Share Posted November 7, 2013 Also, I've never ever used the word 'folly' in its correct usage on an internet forum before. Huzzah for me! Quote Link to comment Share on other sites More sharing options...

I agree that it might not make 'that' much difference dropping the profile down by 5 but it is cutting corners So the speedometer - Use a sat nav for true speed as the car is out +/- 3% anyway, mileage - not exactly a huge concern as the effect will be tiny, traction control - If you really have an issue drive without it, if you rely on it you shouldn't be driving the car, torque - is produced by the engine and not the tyres, so the effect is miniscule and gearing settings - unless you're going from a 15" alloy to a 18" alloy the difference will again, tiny! are all based on the distance that the tyre travels over one complete revolution. - Over a mile the 45 profile will rotate 756.3 times, on the 40 profile the tyre will rotate 784.6 times. Not a huge difference! A tyre with a different outside diameter will travel a different distance over that one revolution with a different amount of torque. Speedo differences for you: 20 - 19.3 30 - 28.9 40 - 38.5 50 - 48.1 60 - 57.8 70 - 67.4 80 - 77 90 - 86.6 2 Quote Link to comment Share on other sites More sharing options...

Its less than 1% out aswell, where as this is 3.7% Quote Link to comment Share on other sites More sharing options...

I personally don't have a problem with it but isn't it cutting corners? Surely you should stick to Oem wheels. Can't say much else the posts above are spot on. It makes such little difference to alot of thr stuff but makes a big difference to weight. Pick up a wheel with 45'd compared to 40's. Heavier which is unsparing weight. Less sidewall distortion so a more positive turn in. The also look way way way better. Edited November 7, 2013 by Dblock Quote Link to comment Share on other sites More sharing options...

They match all the right tolerances/specs needed, exactly the same as OEM wheels. Unfortunately the same can't be said for 40 to 45 profile. If the wheels had wobbly bolts then I get your point but they don't.... Just admit you cut a corner to save £120?! Go on it isn't that hard to say! I will go first if it helps....'I couldn't justify spending £2k+ on Volks so I bought Rotas instead'.

Ride comfort is better too bonus! and theres a lil bit more rubber sticking out over the rim to stop me curbing lol compared to the 35s which sit flush with the rim.

SamN Posted November 7, 2013 Share Posted November 7, 2013 Didn't Kyle compare the weights from 19" rota grid drifts and rays, and confirm that the rotas were only minimally heavier? In either case, rays plus spacers (to get the wider stance) must be similar weights to those rotas and would therefore cause the same extra strain on wheel bearings. Considering how awesome rota grid drifts look, they're definitely worth it in my opinion! Anyway back on topic for more pictures of 40 profiles?? 1 Quote Link to comment Share on other sites More sharing options...
