914World.com _ 914World Garage _ What size tires should I put on the rear?

Posted by: Andyrew Feb 13 2006, 01:02 PM

I'll be putting 255 40 17's up front

Im leaning towards 275 40 18's because of price and diameter of tire.
And this tire.http://www.discounttiredirect.com/direct/findTireDetail.do?sw=false&cs=275&pc=28809&rd=18&ar=40

The taller diameter would also increase the contact patch as well...

Next size up would be. http://www.discounttiredirect.com/direct/findTireDetail.do?sw=false&cs=285&pc=28813&rd=18&ar=35

oh and discount tire has free shipping...

What do you guys think?

i'd try to pick a size that is an OEM size so a few years down the road you don't get stuck looking for a hard to find size.....

bigger is better

I chose 996:
225-35-18 F
295-30-18 R

More common Boxster sizes are slightly narrower

Ironically some of us (Roger) got our flares and are sizing the tires or spacers to fill them out ...I did it with my Chalon.

This time I chose the wheel size and had the flares match them...

Regardless of what size you choose, you will be very happy with the Falkens. I had a set on the BMW and loved them. I have 275/40 R17 for the back of the 914 just waiting for flares....

And if you pick an oddball size the first time you can always opt for the OEM size that is available when its time to re-shoe.....

I vote 285x30x18 on rear...cuz that's what I have

But really, get whatever you can get the best deal on...you can always change the tire size next time you buy tires (like mrdezyne said). I happened to find a deal on ebay for mine so I went with them.

There is also gear ratio's do deal with, and pot holes..

I WILL bend an 18'in rim on 30 series tires. AND it would make my 80mph rpms go even higher than 3.2krpm...

BTW.. 295 30 18's... are ehem.. almost non avalible.. and 2x as much money for barely any more tire..

Oh yes.

I have a measured 11.5in between the fenders. More if I cut the 1/2 in lip.
