Largest Wheel Size And Tyre Size

[skybt1]

Just wondering what is the biggest wheel, in width not diameter that i can fit to my rear end, and what tyre size?

[DR JOSH]

You want the biggest? These aren't the biggest in diameter but 17"x9" front 17"x10" rear is decent size in my books.

We have been down this track just so often it's getting BORING!!!!!

The PJR cars of Glenn Seton & George Fury plus others ran 17 x 9 front and 17 x 10 rear with 240/625 front and 240/650 rear slicks.

For the uninformed these designations mean 240mm wide (bag to bag) same as in normal tyre sizing x 625 & 650mm diameter, that's overall static diameter.

The OPTIMUM tyre size is 245/45 x 16. This gives the largest footprint and is still within 10% of the original tyre size of 195/60 x 15 and the TEST (recommended) rim size for 245/45 x 16 is 8 inches, so my call is the wheels to have are 16 x 8 all round if possible.

My road wheels are 16 x 8 rear and 16 x 7 front using 225/50 rear and 205/55 front.

My track wheels are custom modified BBS Lorinzer wheels of 16 x 8 all round with 245/45 x 16 tyres.

For the strip (drags) I have a pair of Mickey Thompson ET Drag Radials 265/50 x 16 and the recommended wheel for these is also 8 inches wide.

Looking at DrJosh's pics, I'm suggesting the tyres on his wheels are about 225 wide, due to the excessive stretch on the side walls. Stretch like this on a road car does nothing more than expose the side walls to infinite amounts of damage from an infinite range of sources.

Make up your own mind, but staying within 10% of original, which is mandatory in NSW, any 17", 18" or bigger rim will use a narrower tyre and similarly down to original 15's.

JMHO

Close!! It's a 235 hehe.

I'll be the first to say those wheels are just poser value. Look's good though hey. But for perfect track use my wheel of choice would be as ghostrider said a good old 16"x8", it's good to have a few sets of wheels to choose from.

These are my wheels collection:

The 5 star wheels are Monza Racing Rims and I use them for street use. The dark silver are the BBS Lorinzer wheels I use for track and the Silver Advans I just recently sourced to use as drag rims.

so 16x8 seems the go. What sort of offset??

i drove the HR around with 17" x 8" +22 on the rear and they were a good fit. i've just bought a set of 18" x 8.5" +20 and when they arrive i'll wack them on the HR and take some pics.

My 16 x 8's are +38mm and they're a tight fit under the rear guards
