I have a GS450h and would like to fit tyres with a higher profile.
Car is fitted with 245/40ZR18 Pirelli…
Any suggestions?

I'm not sure a higher profile (fatter) tire would fit. If you want lower profile (skinnier tires) than you would need to get new wheels. Most are running 19's. I find that the stock size provides the the best compromise ride/performance trade off but that is just me. I just threw on some Michelin Pilot Super Sports 245/40/18 and they have provided an upgrade in grip without the choppy ride that bigger wheels and skinnier tires cause. Either way...if you want a lower profile tires buy wheels.
