Get the tremec phone app, it'll give you all tyre sizes

Going by the numbers, your overall diameter on the current ones is:
(0.85+0.85)*235 = 399.5mm 399.5/25.4 = 15.7" 15.7+16-31.7" And the new ones: (0.65+0.65)*265 = 344.5mm 344.5/25.4 = 13.6" 13.6+18 = 31.6" Your new wheel and tyre combination is all of 0.1" or 2mm of a reduction in diameter over the old ones which is less than the amount of wear you get in a tyre. That's really not an issue and won't noticeably change the height. |

Wheel diameter will be the same give or take a few mm. You'll need your maths so not to work out how much more the 18" alloys and tyres will cost you compared to 16".

Someone double check please but:
original from axle minus new from axle: 8*25.4 + 235*0.85 - 9*25.4 - 265*0.65 = 2.1mm Solved the bowel problem, working on the consonants... Last edited by agentmulder on 22nd Sep 2016 9:00pm. Edited 1 time in total |

Thanks all.
Cupboard - that's what I wanted to hear. ![]() JOW - cost? Don't. It all began as a very different prospect than what it ended up as. Wheels are the cherry. |

Just for the sake of crossing eyes and dotting teas, keep in mind that only half of that determines vehicle height. Solved the bowel problem, working on the consonants... |

TJ , AgentMulder,
Ti-Fat Man on here would concur that I have been known to change 2mm spacers on mountain bikes and 'feel' a difference…. ![]() ![]() Thanks all. Really helpful as ever. |

The Bowler 18" in anthracite is my absolute favourite wheel. Whilst I might justify to myself the one off extra cost of the alloys, the 18" tyres are 30% more than the equivalent 16", for less tyres!?! KO2 in 16" are roughly £132 where as 18" are £176!! Could I justify this?? I don't know.... Tempting
