Hi all - I'm a complete NOOB when it comes to wheels, I've only ever had stock wheels on my cars. Would there be any issues putting the following on my car?

2012 RX350 Wheels
245/40/R18
Pirelli Cinturato P7
35mm Offset
5 x 114.3 / 4.5

Would I be able to use current lugs? I have 235/45/R17 on chrome wheels now, seem to get bent pretty often.

Any advice is appreciated.

 

Damn bro wheels arent very easy to bend maybe try changing your driving habbits or get the stock 16s 6spoke wheels and u will have a nice fat tire

 

Also those rx tires are 40 u currently have 45 that meAns the rx tire is thinner then what you already have and I belibe you can put rx wheels on a gs according to lug pattern specs u gave me

 

Thanks - must be the potholes in Cincinnati eating me up.

 

While you're right that the 245/40 has a smaller sidewall than the 235/45...your statement above is incorrect and reflects a common misconception about the second number in a tire's measurements.

The "40" and "45" we're referring to here are aspect ratios. They're not static measurements. The sidewall of a 245/40 is 98mm because 245 * .40 = 98. The sidewall of the 235/45 is ~106mm because 235 * .45 = ~106.

This becomes confusing when dealing with tires of greatly differing section widths. Sometimes the tire with the smaller AR has a bigger or the same sized sidewall.

Just tossing this info out there so that the OP (who doesn't seem to have a ton of experience with custom wheels and tires) can be properly educated.

 

well if you want to get into details then yes you are right but the original poster is a noob and i did not want to get him more confused then what he already was so i just stated something simple and understandable
