I found a good deal on this tire size but im wondering if a tire this wide will rub on full turns of the steering wheel.
has anyone used this size?
hoppy halidays to you all

 

Recommended is 225/45/17 so the 245 will have bigger diameter, it is just within the 3% max difference but could be better looking at 245/40? Will make speedo read low by about 3mph.
Not sure about rubbing with 245 but maybe others will know?

 

I went with those on my 2002. I liked the wider stance. The only rubbing I have is on a hard lock turn in the parking lot. Full over will rub but it is very infrequent. I have never had a rub during normal operation.

 

Thanks guys and merry christmas to you

 

I run 225/40/18. Main rubbing is to the plastic inner wells, and I have rolled each fender with them, easy to fix but you lose some paint chips doing it. Drive with care and you should be fine, but it only takes one unnoticed bump during a turn to cause an issue.
And once fender lip is rolled out it is like a tire shaving machine during turns until fixed, skinny lil strips of rubber get sheared right off.
Fullway HP108 tires on ebay are like $125 a pair to your door, 2016 production dates. I run them now and HP198 in the past, the Jag and my wallet like them.

 

Its an interesting engineering challenge. Wider tires will improve traction in the wet specially for the 3.0. One of the things to make it competitive against the BMW 3.

 

Hmmm, learn something new every day - that's the trouble with dementia!


I always thought a tyre was:-


225 or 245 (in this case) was the width
45 - is the Height
17 - Wheel rim diameter


Thus a 245 is wider than a 225 but 45 on both means the same tyre height on the same wheel diameter. Maths would make that the same rolling circumference but obviously the tyre trade is different.

Where you are getting confused is the second number. That is not a dimension (like in millimeters) that is a fixed amount, but instead a ratio/percentage. In this case it is a ratio to the width of the tire. So, the height of the sidewall of a 205/40/17 tire would be 80mm. On a 225 tire that would be 90mm; an 8mm difference. Then figuring the circumference you would double that adding 16mm more to the overall circumference of the 225/40/17 tire compared to the 205/40/17 tire.

 

Yep as Alfadude said it is called Aspect ratio and changes with height.

That's why most 4x4 have tyres with aspect ratio of 65 or 70 you can see the tall sidewall.
