NO 225 is the width in mm i think the percentage is the profile size so a 225/40/18 the 40 is a percentage of the 225 wide...

manufacturers send cars out of the factory with different size wheels let alone tyres front to back, it has nothing to do with the abs! abs sensor works on the axel not front to back it works left to right, if the front left wheel is spinning and the one on the front right isnt then the abs kicks in to stop the wheels locking up... or of the fronts have both stopped but the rears move then it fires to stop locking up, it wont monitor the speeds front to back, as if it did that when you pull off and spin the wheels the abs would kick in...

its et12 17x9.5j all round in each corner mate! car drives, brakes handles mint as it should! granted with 9.5s up front its a lil harder to turn but nothing to bad!

yeah the profile/side wall is worked off a percentage

your missing the point malice yes you can have different wheels but thats were the tyres need to be profiled the same like just and example not sure if its correct but a front with a 235 50 17 might have the same radius as a 225 40 18 then the radius would match due to the percentage of tyre covering up the inch difference . with envys car he has same 18 9.5 front and rear but he has a 225 on front and 235 on rear making the rear radius larger meaning the abs sensor would see the rear turning slower than the front thinking its either skiding or fooked . so i was asking if the abs still works or is this such a small difference that the abs ignores the fualt ?

but your missing my point, if the abs took notice of that, when you dump the clutch and spin wheels on a rx7 the rears are spinning and the fronts not moving or hardly moving then given your theory it would do the same... the abs works per axel and only under braking... it senses left to right not front to back.

the only time you need to concern yourself that the front and rear tyres have the same rolling circumference is if the car is 4wd because the difference puts strain on the transfer box.

for a rwd or fwd it makes no difference at all as malice says, now put some wide wheels on that car!!

uhuh guys your wrong i had a modded audi a4 before the rex and i toyed with the idea of different rims and tyres and i changed the profile front to back and the abs went spastic it knew front to back left to right ..
of course malice when you accelerate and spin up the rears the abs isnt concerned because you arnt braking....... antilocking braking system "abs" ? but abs does work left to right front to back .other wise ice on the road would have to be uniform for the car to stop or the abs to work and  it doesnt so the abs can stop the wheels sliding and keep grip /traction to the ones that arnt .
and toasty yes  the only reason you have to keep the tyre sizes correct on a 4x4 is because of the rolling radius other wise you d get axel spin up and the travel between radiuses wouldnt match and you can mash the box  .
i did a course on this and worked on braking systems for quiet some years  so i was confused as to why  envy s car ran  a larger rolling radius at the back but obviously the guy has no trouble and the stance is mint . so back on track d1  s who wants em lol
