I have a 17 x 8" wheel with a 50mm offset, so clearance is not a problem. What about ride handling accceleration etc????

 

i think it would work fine. your car may pull even more in the ruts though.

 

Better acceleration from lower effective gear ratio.

Generally lower inertial mass (better acceleration).


Wider footprint, but lower diameter means fit could be better or worse (if not lowered, it works on at least one members car [245/40-17 Toyo T1-S + 17 x 8" +48 SSR Type C]).

Slightly better handling...

Ask Technique if he is still around...

 

i'd go w/ 235 brian, last time i saw ur tires they looked like they had lots of tread, r u lookin for new ones now??

 

Yes Darrin,

I will be purchasing these soon. Probably the Michelin Pilots.

The nittos will be put on the stock rims for doing Autocross next summer.

 

oh i see, u still gettin the G cooupe

 

Don't know about the G coupe. It is nice not having a 600 car payment.

Plus I just bought a new winter ride so I'll be doing it up with sound and toys like the rest of my cars.

 

mattg....What do you mean by "pull in the ruts"

 

in like the groves of the road, the car will pull into them more...

thats what i assume

 

245/45/17 is the correct size for the TL/CL

 

Actually if yo0u do the numbers, the 235/45/17 is almost EXACT match to stocks.... ie less than 0.3% error

 

Depends which "stock" you mean. The TL/CL came out first so in all liklihood, the speedo/odo are calibrated to 25.685 inches (205/60/16) meaning that all Type S come with tires that are 0.2 inches smaller than spec.

I'd say 235/45/17 is clearly fine (25.3 inches) but 245/40/17 might be a bit small (24.7)

 

I just brought a set of Toyo Proxy 4 235/45/17 and they are great.

 

Some folks have tested their speedos and they were dead on with the 215/50-17s.

The loaded radius and/or revs/mile would be the best indicator of actual speedo error.

245/40-17 might be a tad small, but it has reduced rotational inertia, increased effective torque, and better chance of fitting with wider wheels.

It all depends on what someone is "going for"...

YMMV
