Bigger wheels and tires

[Lennon]

I have 2015 Ram 1500 5.7L Big Horn, Stock suspension, i just put on some 20x10 wheels -18 offset and 305/55/20 tires. i am about 1.25" - 1.5" out past fenders, little bit of rubbing on wheel well liner, no biggie. Feels heavy, little bit sluggish and less rebound in potholes (stiffer).

What can i add to the truck to compensate for the extra weight of the wheels and tires, what suspension and steering upgrades should i install to reduce strain on truck if any?

Am i worrying about this too much and should just drive?

It may be time for some Bilstein 5100 adjustable shocks up front and some flares to handle the rubbing and prevent damage to the body side panels and rockers.

The extra weight is something that a tuning package can help with. It's a lot cheaper than upgrading the differential gears.

Thank you for the reply, i have had bilsteins on my to do list, flares definitely a must.

As far as tuning package, do you mean a computer tuner? Any recommendations on a tuner? Would not mind paying extra for one that is worth it.

And what else would replacing differentials entail?

Thanks again for your time and replies
