  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Will 245/40/20 fit my 09 Genesis or does it have to be 245/35/20?

Yes they'll fit you'll just be gaining a bit more sidewall and on 20 inch rims this may cause slight rubbing depending on your offset
 
The 40 series tire will fit just fine. One thing to consider:

In general, you want to stay within 3% of your original sidewall diameter when changing tires/wheels for an accurate speedometer. The difference between your 35 vs 40 series is 3.6%.

With the new 40 series tires mounted, this means when your speedometer shows 60mph, your actual speed will be 62.16mph. It's not a big deal unless the slightly inaccurate speedometer/odometer bothers you.

Yup very correct they fit perfect. Thanks. That being said will 255s fit? Or will the front need modifications so it doesn't rub?

Again depends on front wheel specs
Size width and offset
 
Will they fit yes. Is it necessary? Probably not haha
