You worry too much.

There's plenty of people who end up using LT rated tires that are likely DOUBLE the stock tire rating.

 

No problem at all. LT's are less likely to puncture, but you pay for it with ride quality. A passenger tire will give a softer ride than an LT tire.

 

Tires are not your performance issue. And If you plan to do any towing or hauling heavy loads an LT tire is better, anywho. Enjoy your Jeep

2008 Jeep Grand Cherokee Limited 4.7

I bought this with worn out Goodyear Fortera tires which had several plugs in the back (one of my annoyances i wont tolerate a tire that puncture easily especially brand name tires).

I got a deal on set of Yokohama Geolander 55 SUV Model (245/65/17) but were a higher load tire at 107 rating vs stock recommendation of 105 not knowing that was a bad thing to increase load. I have poorer braking and acceleration if thats even possible probably cause of new thread vs. balding worn Fortera's before.

Should I bite the bullet and get rid of this Yokohama's with the higher weight rating as everything i read says never go above or below manufacture's recommendations.. I was thinking of going with Goodyear Wranger SRA's.. yes more than double expense and mounting costs again..

Your thoughts?

Hi
I really would not let it bother you. 105 and 107 are so close difference should be negligible. The 'H' rating is much better too and is a requirement this side of the pond.
