I'm going from ProComp x a/t 33's to Toyo m/t 35's. I'm concerned that these tires will really slow me down. I read that they were heavy. I have a 4 door jk jeep with 4.10's. I really want the toyo's now, but don't want to regear just yet(will need more $). Any suggestions on the gears when I do buy them? I feel like the jeep drives well now. I bought the jeep lifted and with 33's, so I have no idea what the stock drive was like.

 

The rpm difference for a 33" diameter vs a 35" diameter tire is roughly 5-6%....with the larger diameter dropping the rpms and a smaller diameter raising the rpms to maintain a given speed, etc.


Example -

For whatever speed you're at, if you stay at the same speed, but with the 35" instead of the 33" tire, with the following rpm on your tach:

At 3,000 rpm on your tachometer, the 35 would drop the rpm from 3,000 to around 2,820 - 2,850-ish.

At 2,000 RPM, it would drop you to about 1,890-ish, etc.

Hope that helps.

 

I have an auto. Here's a picture.

 

Ur jeep looks good with those half doors......

 

You'll probably notice a difference, but it won't be unbearable.

I have a 4 door Auto on 35"s with the 4.10s and so long as the overdrive is off its pretty quick.

 

You will notice a difference, but it won't be huge or unbearable. I've got the same, auto, 4.10's, 35 " Toyo's. Those tires will look badass on your Jeep! Do it.

 

Damn, I love the wheel and Color choice!

 

I have 35in Cooper STT's about the same as the Toyo's. Also have 4.10's, like Deep sky said , press the OD button off and you'll be good.

 

Here's mine

 

35's, 4.10's, and an auto aren't too much fun on the highway if you come to any kind of inclines. The tranny likes to kick down into 3rd quite a bit in that case. If you don't mind that you will be fine.
