Many forum members have replaced their rear tire with the avon 240.And they all seem to agree that the Raider handles better with it than with the stock 210.Today,I joined the 240 club and installed my avon 240...step 1 on my list of winter mods.Can't wait to try it.Come on,summer....
I've often wondered what size difference I should expect,but I couldn't find any tread on the subject.So I got a straightedge,a framer's square.and a tape measure.Keep in mind that the method wasn't very scientific,and only done using basic tools,nothing fancy,so results might not be extra precise.But the results still give me a pretty good idea. FYI mounted tires were inflated to 42psi.
My old tire>>>Bridgestone Exedra G852 210/40r18
My new tire>>>Avon Cobra AV72 240/40r18
Width>>>>>>>>>>>>>>>unmounted>>>>>>>>>>>>>>>>mounted
Bridgestone 211mm or 8.30709" 213mm or 8.38583"
Avon 235mm or 9.25197" 230mm or 9.05512"
I was surprised to see that the 210 was actually wider mounted than unmounted.I guess the air pressure stretches it a bit.The 7.5" (190.5mm) wheel,although very close,is still slightly narrower than the 210 by almost an inch.I did however expect the 240 to be thinner than 240mm when installed because the 7.5" wheel is much thinner than the tire,but what surprised me was that it wasn't even 240mm wide in the first place.So in the end,my installed 240 rear is actually a 230.
As for height,I didn't pay too much attention to it.After all,I am comparing a new tire to an old one with a 1½" wide flat groove down the middle.But needless to say the 240 looks huge next to the 210.I measured height anyway just for fun.
Height>>>>>>>>>>>>>>unmounted>>>>>>>>>>>>>>>>mounted
Bridgestone 609mm or 23.9764" 616mm or 24.2520"
Avon 641mm or 25.2362" 646mm or 25.4331"
Interesting observation:Both tires are 5mm taller when installed.I expected the 240 to have a greater installed/uninstalled height difference since the wheel was keeping it thinner than it's 240 rating,but I guess the tire's carcass can only go so far.
On a final note:After comparing tread depth between both tires,I can speculate that the old tire lost ½" in total height ( 8/32" top and 8/32" bottom) which would mean that the Avon 240 is just shy of 3/4" taller than a new Bridgestone 210,installed or not.
