Hey all,

Quick question.

If I went from a stock 32" to a 33". Do I need to adjust my speedo with the procal?

Will it make that much of a difference? The speedo is off by about 3-5kms/hr.

Will it through off the ESP that much?

 

no, it won't make that much of a difference as your speedo will just be silghtly off but it is nice to have it accurate and it should help keep your shift points correct if you have an auto. it won't make a difference in your esp as it does not control it but it will allow you to set your steering if it is off after installing a lift and your steering being off will trigger your esp. also, it will allow you to set your tpms to a lower setting or turn it off all together.

 

I noticed that sometimes the esp goes off on "on ramps". Does that mean it could going off for because of something else?

 

if your esp triggers on on-ramps, you most likley are running too much air in your tires. for 32's, if you are running more than about 30-32 psi, you are running too much air. if your jeep is lifted with a budget boost, it's possible that your steering wheel might be slightly off as well.

 

I am running 33" Goodyear Duratrac's (275/70R18) on my stock rims.....I have 1.5" wheels spacers as I was getting some rubbing.....


No lift yet.....what PSI should I be running on my 33's?

 

I am running same tire setup as you have. Been running 28 psi to get a better ride out of the e-rated tires. Used the procal to lower the TPMS to 24 psi.
