wheels touching slightly advice needed

so the 20inch DPE reps i had on the car needed tyres

i managed to get a good deal on 275 30 20 rear and 245 35 20 front

rear rims are 10j et40

front are 8.5 et35
they are touching when i go over bumps would rolling the arches solve my problem??

btw its a e90 lci

thanks
