A tyre's aspect ratio is in relation to width. If the width is greater then this value is relative. The sidewall of a 295mm would be 177mm versus 165mm on a 275mm wide tyre. Based on a 40% aspect ratio.

Definately go with the 295's. I have them and not only do you have a bit more sidewall, the extra width will help with curbs etc as the tyre has to be squashed more before you can damage the rim. |

JE would strongly recommend the 295/40 20 option, and this size is availble from Hankook in RH06 type |

Thanks alot for all your responses. I think i'm gonna go for the 295 option and probably with conti's. The replica's seem to be 9.5 wide so the side wall won't be perfectly straight but close enough!

Would the difference in the overal tyre ratio affect the final readings on speedometre / trip computer etc etc ? |

I was wandering this aswell. As the OEM 20" are -10mm, do Land Rover re-programme the speedo and trip computer for cars with those wheels? I very much doubt it! Check this out: http://www.tyresave.co.uk/tyresize.html It seems that any change which is within +/- 2.5% is pretty insignificant. Once I change wheels I'll hook up my Garmin GPS to check how precise the cars speedo is. |

I've recently upgraded from 275/40 to 295/40 Goodyear F1 Wranglers onto my 20" Supercharged rims without any problems. The extra tread width looks great, the higher tyrewall fills the wheel-arch better, and the ride seems more sure-footed without feeling heavier.

"[Also, as rolling circumference has increased and the speedo readout reduced, I'm informed the recorded mileage may theoretically diminish by the corresponding percentage (ie 10,000miles would drop to 9,000'ish.., please correct me if I'm wrong).

Whilst the increased circumference = reduced mileage principle is sound, I share your suspicion that it'll probably be negligible, if anything (more wishful thinking perhaps??). With regard pix, there appears no facility for normal picture uploading onto this website without complications? Shame, because I also wanted to show the recently installed Rossini drilled and grooved discs alongside the 20"wheel+295/40 tyre combination.., nice! |

Ok, I saw a car with 22" Stormer replica's and am now toying with the idea!!
