4.10s vs tire size

[Blk04MM]

When dealing with gears especially in the Marauder. At what point do the tire size start to cancel out the performance of getting a lower gear ratio?

4.10 will turn a 245/55 with a very noticeable difference. At what point should one should go 4.30?

Some guys have upgraded to 19+ inch rim size. And some have went with a bigger overall tire diameter.

My new tires will be 245/60 (only because I got them for $40 new) which is only a tad bit bigger then stock. So I shouldn't have a performance issue.

I'm just curious

I'm running 255/55s in the rear and no issues with performance using 4.10s.

The difference between 4.10s and 4.30s is 4.89%. That means if the tire height (and therefore also tire diameter) decreases below 95.11% of that of the OEM rear size, you have lost the advantage of 4.10s.

OEM stock rears are 28.61 inches tall. So, you shouldn't go any smaller than 27.28 inches. With a 19" rim, that is a pretty small aspect ratio.... probably below 35 and lower.

Mathematically, the 28.61" OEM size with 4.10s should perform and give the same launch feel as the 27.28" tires with 4.30s.

Ok

Got cha. I was just curious about all this.

Running a 245/60 with 4.10 gears will put you around 4.05 +/- effective rear gear ratio.

I have 265/50 with 4.10s and my effective rear gear ratio is 4.15.
