    I KNOW there are a MILLION questions regarding 19" wheels. I would like (If I can) to keep my 19" wheels and just get a BEEFIER tire but need to know the largest size I can get with out any rubbing or any modifications. I know I can get the GoodYear DuraTech 255/55/19 BUT can I get any larger than that??? I don't want to but 18" wheels unless I absolutley have no other options. Thank you in advance! Angela W.

    Your options will be limited regardless, especially in "beefy". However, the larger sizes available in 19" that will not rub are both about 31" tires, 275/55/19 and 255/60/19.

    You can search around for other sizes from smaller manufacturers as well - basically things are rub-free until ~31.4" tall. The stock tires are 30".

    You can browse "most" of the available styles in each size here:

    However, the 275 section is not meant to be on the factory 8" wide wheels. At least 19's are a super easy tire choice, because there are basically only 2 sizes and they both fit LOL. Only good use for 19's is highway travel and basic forest roads or winter, but for those uses, they sure do let the vehicle feel peppy because they don't weigh much at all.

    There's the Atturo Trail Blade M/T. Not bigger, they actually run slightly smaller (in height and width), it's a mud tire, so you could consider it "beefier". Definitely more aggressive, it's a 255/55r19

    I looked into this earlier. One option is to run 255/60/19 on the stock wheels. This gives you an inch more diameter and you get more sidewall. There is an L322 Range Rover near my work that runs this size tire and looks great. The main issue I saw with this size is that it's hard to find tires with an appropriate load rating for the LR4, as you need XL/111+ per tire. Also the tire choices are severely limited in this size. I gave up looking after a while and am now eyeing some 18s with the trial-tested size of 265/65/18.

    The 275/55/19 tires are rated for 7.5"-9.5" wheels, they will fit fine on an 8" wheel. They might bulge a hair more but will mount ok and be safe. Unless you were referring to the potential for rubbing because they are a bit wider...

    Nah, not fine. Bulging is crap and means tires were poorly chosen. The weight of this vehicle will exaggerate that sort of bad sizing and make the handling suck. When the RRS comes with 275's it's on a 9 to 9.5" wide wheel, never on an 8", not from the factory.

    Will it mount and is it within the noted spec, sure, is it smart, no not at all in this scenario. Maybe on a lightweight bmw but not under 5800 lbs. There is simply no sense whatsoever to choose a bad ratio.

    Well, it really is dependent on sidewall height. For example, the stock 275/40/22 on a RR is on 9.5" wheel where the spec is 9"-11" (10" being ideal). This is akin to the 275/55/19 tire on an LR4 in that both are one size off "ideal" wheel width and one size up from the lowest allowed wheel width. The 22" tire below would have more "bulge" than the same tire on a 10" wheel, but hardly a concern (in my opinion), it certainly does not look bulgy in the photo. In theory as the sidewall height increases the aesthetic of the bulge may become more pronounced and there "technically" could be handling implications, but usually within manufacturer specs (of which they ALL use the same range of wheel sizes) there is not a significant difference.

    Even the base model size of 255/55/20 is on an 8.5 wheel, where the spec for that size tire is 7"-9", so in this case the tire will run a touch more narrow than the "ideal" 8" wide wheel.

    I can't argue the semantics of those differences because that would depend on the specific tire itself and how it is driven. But overall I would not be afraid of a 275/55/19 tire, the sidewall is still relatively small compared to a 33" tire on a 16" wheel.

    I appreciate the post of all that useful data. However, my own experience on different tire shapes says 275/55 will actually be noticeable and I would think it sucks on how it feels. The sidewall is plenty tall enough to make a difference too.

    I told you above, on a lighter car I could feel the difference, surprisingly to me, between a 255/40-18 which truly sucked, horrible, and the stock 245/40. Now, it was 2 different brand tires, but you could actually see the shape tapered into the rim lip from the tread outer edge. This was on an 8" wheel. You could feel the whole car make an initial weight shift starting into a corner. Now, on a boring vehicle or taking it super slow, you probably would never notice until you had to avoid a deer then the thing would actually contribute to over-steer because most people do some anyway when surprised.

    This "lurch" of the weight, then back when you try to correct, is not my idea of a good handling tire spec.

    On the very same wheel I then went to a 245/45x18 and it was night n day. Of course the psi were double checked, and various scenarios were tested mimicking panic avoidance and hard cornering approaches. These were easy to feel due to the tight handling of the bmw suspension and chassis.

    Then I put that size tire, 245/45x18 onto an 8.5x18 and the tightness was even sharper. Perfect really. The shape was not like a "stretched" tire but it did have a perfect gentle angle from tread edge to rim lip.

    Since then I put on new winters on the 8" wheel, 245/45 again but in Nokian and even RFT but they are constructed a bit wide at the tread o they still have an inverse shape a little.

    Overall, the tire brand and model will likely matter in this idea but I am sure there is no 275/55x19 that will be doing it's very best performance on an 8" wheel. 9-9.5" sure, would be perfect.
