Wider tyres on 2014 XLT 5.4L

\​

Hi All,

I inherited a 2014 XLT with 185,000kms and regularly maintained. I'm gradually working on making it look a bit better as mechanicallly it's sound.

The car is on 25570R18 tyres on stock rims. The tyres still have some life in them and I'm researching if I can add a slightly larger tyre without compromising the ride and handling.

After some research, I decided to use the existing rims after cleaning and painting and put slightly larger 27570R18 tyres , is this a good idea ?

I've read that the grip will increase with the wider track but it would potentially make the steering harder and considering the 5.4L is not known for speed would make the car even more sluggish.

To add, I will only for highway driving and around town with no off-roading or bad weather and stuff.

I was also considering a slight lift of 1.5-2 inches but I don't want to compromise the ride as I genuinely enjoy driving the car the way it is but would love a lift.

Thanks all in advance.
