Right now the rims are lowenhart LDR, they have 275/30/19 and 245/40/19

I just bought tires 275/45/19 and 245/45/19 will they fit on the wheels just fine?

the tires will fit the rims, but it will mess up the distance you travel per rotation of the rim. Basically you will be rolling at a rate of a grapfruit rather than an orange, see the difference? And chances are you will be traveling at a faster speed than what your speedometer says, but not that much faster.

Will I have any vibrations or so on?

What did your chip do for your car?

The difference between 275/30/19 and 275/45/19 is huge - 12.7%. Not only will it throw the speedometer off (100 km/h on speedo = 112.7 km/h actual), but you will likely have clearance/rubbing issues as well.

Luke@tirerack

ther proper sizes for your car would be 285/35-19 rear and 245/40-19 front but, the 275/35-19 would work
