Don't start flamin me pple, its just some i noticed, or at least I think I noticed...

I've got 16" wheels with 205/40's on them, and since the tire is a little smaller than the stock tire, it seems as if I pick up speed faster of the line. I mean, it almost makes sense doesn't it? a bigger tire takes longer to make one whole turn around, as appose to a smaller tire which will make one whole turn faster?!

It could be just me and my immagination, but it almost makes sense when I was thinking about it.

If anyone has any input, (and I'm sure you pple will) it would be appreciated, even if you can prove me wrong

Thanx, Mike

A smaller tire isn't going to GIVE you any more horsepower or torque on a dyno but yes, i do see where you are coming from the logic seems that it should be happening like that but I don't know for sure.

seriously were you bored when you were thinking about this? You wont feel much of a difference in Torque with the new tires. Next topic...

Proof that jus cause your a super memeber... dosnt mean you have the right to flame..... if your tryin to cut your times down.. every last part of your car counts so shut up... that bein said... I will flame you however on postin your stupid Q. on everysingle forum this site has... dont do that... (heheh) though I must say I've been chekin responses on each cause I'm lookin for a rim tire combo that will give me the same if not less total weight of our stock tires..

It's a difference in gearing, not a difference in actual engine output. Like changing to a shorter gear ratio.

wrong...

I remember this from physics class... the larger the diameter of the wheel, the faster a car accelerates forward. We used this concept in building mini race carz.
Your engine & drivetrain have to do a little more work in moving a smaller wheel the same distance as a larger one. Example: Like trying to pedal a kiddy bike and keep up with a mountain bike (w/ only one gear on each- no switchin gears crap goin on). You'd have to pedal the hell outta the kiddy bike and you wouldn't get anywhere. => more work but less distance

i think you're just getting better grip with the tires-whatcha think??

Neonmike has the right idea

OR. your rims are lighter than the stock steel rims... that can factor to it.

in either case, ur torque wont increase.. if anything, it may make it easier for the engine to turn the wheels.

you wont get more torque ull just get more grip b/c of the larger wheel in result better launch.

You seemed to have forgotten the other most important aspect, the weight of the fricken wheel! Doh!!
