Need help with new Tires
Mods can you leave this here just for a little while... I am hoping to order these tonight...
I plan on getting new tires from the rack tonight for my new Salina's...
Should I go with the factory spec size or a little taller sidewall to improve comfort?
Anyone with size recomendations would be appreciated.
Factory sizes are...
Fronts - 235/40/18
Rears - 265/35/18
I plan on getting the BFGoodrich g-Force Sport which recieved good reviews for tread life, low noise, and wet/dry traction from most reviews on the site... This is mainly a price decision but nice to see that in this case few $$$ buy a decent tire.
Also, can anyone confirm if the lug on the left in the picture in this thread is the factory lug and not something L-Tuned and special...

The ideal setup for 18's is 245/40 front and 275/35 rear. I'm assuming your salina's in the rear are at least 9" wide. If not, your better off with 235 or 245 on all four rims if they are 8 or 8.5

you know about this, right? http://www.miata.net/garage/tirecalcold.html
I have 245-40-18 Pirelli Pzero neros and they are comfy. I know your rears are bigger so according to my calculations, 275-35 rear and 235 40 front are your best bet. that way, the rear tire is only .1 of an inch taller than front

gs are 225/55/16 which is 25.7. That's why a 245/40 and 275/35 in 18's are the ideal setup

What about these sizes as compared to stock?
Tire Size Comparison
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
Stock - 225/55-16 4.9in 12.9in 25.7in 80.9in 783 0.0%
Front - 245/40-18 3.9in 12.9in 25.7in 80.8in 784 -0.1%
Rear - 285/35-18 3.9in 12.9in 25.9in 81.2in 780 0.4%
Diameter is now .2 inches taller instead of .1 shorter in rear?
However, doesn't the L-Tuned drop compensate for the .1 inch difference... I thought the official drop was 1 inch front and .9 rear for the L-Tuned shock/spring combo?
Factory L-Tuned sizes were...
Front - 235/40-18 3.7in 12.7in 25.4in 79.8in 794 -1.3%
Rear - 265/35-18 3.7in 12.7in 25.3in 79.5in 797 -1.7%
Note the rear diameter off by that .1 inch...
So maybe the 245/40-18 275/35-18 setup does make the most sense!

And what is your vote? The sizes you were going to go with?

With wider rims (8.5/10), the tires will be more within the tolerance.
And yes, for the Salinas, my vote would be 245/275. If you are worried that it is not OEM, the GS340 Sport edition that is available in Europe comes with the Salinas and they run 245/275. This is a Lexus edition and not an "aftermarket" edition like L-Tuned/TRD.
