Kumho Ecsta v700 $148


Bfg geforce T/A kd $159


Kumho Ecsta MX $104


Pontenza S03 $153


Im leaning toward bfg geforce T/A or the S03.

Reason being, I believe strongly the bfg can hold most of what i throw at it. and the side walls are to stiff or to soft.

S03s being higher ratings, cheaper, longer life.

 

I am going with the V700's. I hear really good things about these tires and I heard they will last awhile too. I thought about the BFG's but they don't last long at all and are more expensive to replace if you have to do it every 5000 miles.

 

Those sizes are large - you will need <40mm offset to clear those

225/40 or 215/45 is the correct aspect ratio for 16"

 

the v700's are race/track/autox tires.

my wheels are 45mm offset

 

ot - would switching from a large size to a smaller wheel/tire or vice versa change the car's alignment?

 

your looking at the wrong size tires,

205 45 16 or 215 45 16 or 225 40 16

 

225/45/16 PZero Assimetricos are also an option and cheaper than all of the above. Amazing tires.

wrong tire size for your wheels... if you have 16's with +45 offset

you should get 215/45/16

Jordo - the tires you a looking at are too big -

Use this : http://miata.net/garage/tirecalc.html

<u>Stock tire size</u> = 195/55-15

Diameter is 595.5 mm Circumference = 1870.8 mm 535 revs/km

<u>Your new size</u> = 225/50-16

Diameter is 631.4 mm Circumference = 1983.6 mm 504 revs/km


Not only are they TOO WIDE and heavy. They are too tall and will give you a 6% speedometer error. They will also hurt acceleration.

215/45-16

Diameter is 599.9 mm Circumference = 1884.6 mm 531 revs/km
which is only a 0.7% difference

i dont thikn 215s are gonna hold 350whp+

 

Jordo-

The shape of the contact patches will not be signficantly different between a 215 section width tire and a 225 section width tire.

The SIZE of the contact patch is determined by the weight of the car - not the size of the tire. This has been discussed on numerous occasions and George Knighton would be happy to re-discuss this topic with you.

If you seek better traction - more gains are to be had from selecting the right tire compound, a better LSD and traction bars if necessary.

Channelling 350 whp through the front tires of a FWD car is going to be a mechanical challenge anyway. Torque steer is going to be a major problem - along with getting all that power to the ground in an effective manner.

Bigger wider tires are only going to worsen torque steer.

 

good info for future tire purchase

Yes they do, and you can also get Michelin Pilot Sport in 215/45/16 but they are $$$$$$$

 

Tires get wider to compensate for softer compounds. The only thing width does is dissipate heat better for soft compound tires.
